I'm building a new PC and I'm conflicted on which GPU I should get. I intend on either getting a GTX 570 or 460 2win. Another option would be to forgo upgrading my keyboard and mouse for 2-3 weeks and use that money to buy a GTX 580. I will game at 1920 x 1080 (not HD) and play games such as Dragon Age 2, Crysis 2, CoD 4, Team Fortress 2, and Battlefield 3 and Skrim when they come out. Any feedback or advice is greatly appreciated!
well the 2win is the most powerfull card out of those you mentioned... also requires the most power....as a single card allows nvidia 3d surround also.....let it be known its frikin huge tho......also you cant add another one because the gf104 chip is a 2gpu max....
and obviously the 580 will best the 570......but for the most par a 570 will be plenty....also you can just add another one down the road when y ou save up a lil more if you find your gfx lacking.....2x 570 in sli > 1x 580
hope that helps
ps just for your knowledge 1920x1080 is definitely HD
Depends on the power supply you plan to purchase for this build.
The 460 2Win card requires 2 PCIe 8-pin power connectors. Tom's also suggests a minimum of a 700W power supply with this card. It would give you a slight performance advantage over the 570 for most games.
If your keyboard and mouse work, I would forgo the upgrade and go with a 580. They are great cards. You know they'll handle whatever you throw at them for at least a couple of years.
I'm purchasing a 750w psu. I've been leaning towards thaa option as well Ubercake, just for sheer upgradability.
A 750W is cutting it close if you'll be considering 580s in SLI. My power requirement for SLI when my GPUs hit in the high 90%s load while gaming is around 660W-670W (appliance load tester is reading around the 780W mark pulling from the wall). If you OC anything, your requirement could add to that requirement. I'd suggest you shoot for an 850W or higher (Corsair-like specs) if you plan to go with 2 580s to be on the safe side:
It's not modular, but will give you what you need. I have the 950w edition. It's solid. I tried to get near 1000W based on advice from so-called "experts" I've seen on these forums, but when I got scientific about it found you need far less for 2 580s (as noted above).
A 650w can give you what you need for any single GPU card. Even a single 580, though a second will push beyond 650W.
