Ok my credit card only has a limit of $500 so I can't order this online. I'll have to go into a store and buy this with cash. I was wanting to buy an off the self model that is upgradable. I was thinking about getting something with an Amd apu so I can play some games while I'm waiting for the r9 295x to come out or getting two gtx 780ti to run in sli. The problem is that it's hard to research my options because the stores don't tell me what motherboard is inside of the tower or how many PCI express slots are on the motherboard. The 295x will be a dual slot and the 780ti is a dual a lot for just one card. That means that I need at least 2 or 4 slots to make this work. Can somebody please recommend an off the shelf model that can fit the graphics card/cards.
