Can't find if it's 1 or 2. Can you download GPU-Z and see for yourself ? You have to hover your cursor over the 'Bus Interface' box for a sec and an info bubble should pop up. ( thanks MM )
I think it's a 1.1 or 1.0 version tho and there is sadly no way of telling than if it will work or not. It probably will, but it ain't sure.
Because of the 2 core i think higher than a 460 makes the cpu bottleneck so no need for a 560. I can be wrong, so forum, correct me if so.
Euh, quad core ? Your sure, i found a couple of the 530 with 2 core. Not your model tho, other models like the e4600.
Cooler Master is ok, but not allways with the cheaper models so i wouldn't.
I have a look at best buy.
I think this one, altough it's officially 30W lower, is a safer choice. But make sure you don't oc anything and don't put 4 hd and 6 fans in ; 430W is very, very close and really not reccomendeble. ( i wouldn't like to take that risk for 20 or 30 bucks actually )
