Considering getting another gtx 560ti

[ihacks]

my current 560ti just died and i sent it in for an rma, i was thinking of getting anther one to use in sli once it came back, but can my psu handle 2 560ti's in sli?
i read that when i sli on my motherboard it runs in x8/x8 does this mean ill lose performance?
my specs are:

antec earthwatts 650
2500k
crucial m4
western black
asus z77 pro

Running at x8/x8 instead of x16/x16 is only like a 5% difference. Someone please correct me if i'm wrong. But your 650watt is not going to be enough. Hear uses neweggs power calculator. http://images10.newegg.com/BizIntell/tool/psucalc/index.html?name=Power-Supply-Wattage-Calculator

would i be cutting it close if i got a 7970 instead, i have my cpu oc'd to 4.7ghz if thats an issue and also 6gb of ram

With one 7970 you should be fine. The nvidia 670 is coming out May 10th. So you can wait for that if you want. Even if you don't get one it will push prices down of the new AMD cards. But one 560ti is still a damn good card. So you can keep just that and still be good. Sell the psu get a new one and another 560ti. Or sell the 560ti and get one really good card 7970, 7950, 670 or 680. Lets hope nvidia can make enough chips so there cards well be in stock.
