is the GTX 260 your talking about one of the regular ones, or one of the newer 216 core models?
just wondering, cause I'd like to know for myself if your PSU will handle it fine, been thinking of grabbing one those monsters for myself if I can, 216 core GTX 260, GTX 280 has 240 & stock GTX 260 only has 192... for close to same price as a standard model if one could get a nicely clocked 260 with the 216 Cores, it'd be a real good replacement for a GTX 280 for way less.
My PSU's a bit more powerful, but I'd like to know anyways...
also wondering what something like that in SLI would require, not that I'll be doing that for sure, but just curious.
