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.
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.
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.
