Ok, you're right, i should get the new GPU first, and yea i was planning on waiting for a while because i won't even have enough money for a while (With New Vegas and whatnot). And then, maybe if i get enough Christmas money, ill be close to getting the CPU.
Also, i think the very first thing i need is a case with the size on these new cards. My 4870 barely fits right now and the 5870 is huge.
Perhaps not. the new GTX460 is 8.5" long.
