ASUS GT640 2GB DDR3 Memory Graphics Cards

Pros: 2 DVI, 1 HDMI, 1 VGA - can run up to 4 monitors at the same time!!!! Excellent card for running multiple monitors, video editing or as an intro gaming card. Can handle 1080p video editing without lag and the giant fan keeps it really cool and quiet. Runs most games in 1920x1200/high graphics (mainly depending on the game) The software that comes with the card is excellent (props to ASUS) - allows for multiple profiles and to over-clock your card automatically when you start up your pc. I believe my power supply is a 350 Watt, and its more then plenty for over-clocking this card + running 2 high-res monitors. 300+ Watt should be enough to run it without any issues if you're not planning to over-clock. Cons: The main thing that you will have to watch out for is the card's physical size (if you have a tight space around your pci-e slot). It doesn't look like it but it's as big as its more powerful cousins. As you can tell from the picture the fan extends past the card itself and is simply put huge, in my case (stock hp) I had to move all the power wires around to make this card fit comfortably (100% worth it). It will take up 2 slots worth of space in your pc. This card doesn't have an sli connector so aside from over-clocking it you won't be able to get higher performance in the future (this shouldn't be an issue for anyone looking to spend less then $100 on a graphics card). I figured this out after purchasing the card, but 2 gbs of video ram is overkill and is more of a selling point then anything: you will never use more then 800-900 mbs simply based on the limitations of the gpu itself. If I could buy this product again, I would probably go for the (faster) 1 gb DDR5 version of the 640 gt or 650 gt card with the same awesome fan and over-clocking software from ASUS. Conclusion: Easy to install and use, awesome quiet fan, excellent overclocking software, (physically) HUGE CARD This is an excellent card for anyone looking to upgrade a stock system, run (many) multiple monitors, or do some mid-level gaming. Great Value for your money.

I've lost one of the video outs. Everything worked fine for a couple of months and then one of the HDMI ports quit working. I reconfigured my desktop and switched things around and it started working again. Now it has dropped off again and I'm too sick of messing with it to fuss with it any further. Since I don't want a dead 27" display I'll probably have to go buy something to replace this beast. Really disappointing.

I'm sort of a high-end office and graphics programs user, not a gamer. The video card in my old ASUS P5WD2-E Premium, an ATI Radeon X1900 GT was bothering me because its fan was overspeeding more and more, making me feel as though it was about to fail and interrupting my train of thought. So, for $99 I jumped on this one, far superior to the other in memory size, speed, picture sharpness and cost, with no external power required. I have not been disappointed by performance, and have not heard its fan once. My use for it so far has been limited to one 24x36" HD monitor, but I will be getting a second to use with a double-monitor setup very soon. One other commenter is planning to use his with 4 monitors, and has been using it successfully with 3, for mostly big spreadsheets. That will more than satisfy my needs. I recommend it highly for less than gaming experience. For all I know, it wiould be satisfactory for entry-level games as well.

I installed this on a new Windows 8.1 based PC. Initially, I had an odd issue of my PC not displaying anything on a monitor hooked up to DVI port. Then I connect another monitor to a VGA port and suddenly the display comes back to both monitors. Same thing happened again when upgrading video driver versions. Windows 8.1 tries to switch video driver versions then I lose my display. I connect something to VGA port and I get my display back. I also noticed, when BIOS boots, it did not display manufacturer's logo. I've called ASUS tech support but the agent I spoke with kept beating around the bush and did not assist me. According to him, it is working, so I had nothing to worry about. It took me 3 days of research and logical deduction to figure this out. Apparently, this video card shipped with a firmware made for traditional BIOS. So when connected to UEFI based machines (which Windows 8 requires), security verification fails, then it goes into this odd behavior. There are two ways to resolve this. 1) Upgrade the firmware on this video card to UEFI ready version 2) Turn off UEFI in BIOS and go back to traditional mode I took the latter route as it was easier. Now everything works as it should. Performance is perfectly acceptable for my use. Having an ability to do dual display is great. I may hook up a third in near future. Conclusion is, this video card, as shipped, is not truly Windows 8 compliant. At least mine was not. If anyone is having odd issues, my suggestion is to verify the BIOS version, then try disabling UEFI bios if possible.

8600GTで動画再生に若干苦しい場面があったので、3Dパフォーマンスで2.2倍のスペックとなる 本製品を購入しました。評判どおり、静かで安定しています。8600GTでの再生不具合は完全に 解消されました。3Dゲームはやらないのでスペック的にはこれで十分です。 嬉しいのはファイアフォックスのハードウエアアクセレーション機能がCUDAをサポートしているので、 ブラウジングがとても快適になりました。 消費電力も少なめで普通のブラウジングならアイドル状態なので10W程度です。8600GTの半分以下ですね。

This card is perfect for my gaming needs, I don't need the highest graphic settings to enjoy a game, but now that I got this card, I can have high settings and no slow down. I would say it's definitely worth the price.

Good product!

Bought it for multi monitors. I have 4 monitors plugged in and everything run smooth. The card doesn't really make noise even if it has a big fan and temperatures are around mid 40 on general tasks and near 60-65 on demanding applications. Must be aware that the card may use 2 slots, so you may end up losing a pci, pci-e slots because the card take that much place. Not recommended for games but you can definitly play games on it, but don't buy it expecting all details will be on high. For 100$, not much to say other than, what a great buy, multi monitors all the way. Recommended for sure.
