I ready to click on checkout but want to be sure to donk mess it up! Please give me the final tought please
The GTX295 will outperform the GTX260 SLI, but if it fits your budget; I would get GTX275 SLI instead of either of those. GTX275 SLI will be better than either of them and should cost ~same if not less than the GTX295.
XFX GTX 260 is on a -$30 sale right now, I'd pick up 2 of those over a GTX295 and save $150-$200, plus 2 card SLI looks sweeter. GTX295 will perform better I believe, but not $200 better. The best comes with a premium!
