alright, so i am upgrading my gtx 260. i thought i was set on the 470 i have now, but am able to return it still so here is my issue. is the 470 worth the extra $40 over the 460 1 gig version? $210 for the 460, $250 for the 470. i may end up in a sli situation later down the road, and will have a better power supply then (corsair 750 i think, maybe 850) and a new motherboard by then as well. wondering since the 460 is a lot cooler than the 470 im wondering if the 470's will get too hot together? and since the 460 in sli is a little more powerful than a 480 and runs cooler, plus cheaper than a 480, i was thinking of doing that. but if 2 470's are alright with good cooling, then that might be the road to take. i just really dont know. i could get the 470 and not have to upgrade anything for a while, but how long to you think a 470 will last before ill want/need to add another? or do you think by then that i will be ready for a newer card again with whatever nvidia has out at that time? i know i seem a little all over the place, but im seriously getting stressed about making the right choice. any and ALL help is greatly appreciated
