1gb vram will be gone the way of the dodo in the next 12 months for 1900x1200 gaming, let alone 2560x1600. Its curious to see people say its not worth getting 2gb 5870s because it doesnt make any difference and if it does its only at very high resolutions and AA levels. Thats true now but it will very likely be incorrect 12 months from now, and theres precedent for such an opinion. The gts 250 is based on some pretty ancient hardware and it can make very good use of 1gb vram on its own, and its a pretty timid bit of kit now. When full g92 chips came out there were a handfull of 1gb models and they looked over the top in their day but they would have matured all the better for having that bit more ram behind them. Check out this old xbitlabs review: http://www.xbitlabs.com/articles/video/display/gainward-bliss8800gts-1024_17.html#sect0 and a comment thread at hardocp of a fudzilla 1gb gts review: http://hardforum.com/showthread.php?t=1278345 In my eyes it all looks spookily familiar to the arguements going on today. Get 2 x 2gb 5870s, as bog standard as you can get all 5870s oc to around the same point, and a 750watt top tier psu. You'll appreciate the extra ram if you plan on holding onto the setup for longer than 9 months from now.
