Yeah, I don't want to sound like a jerk but I agree with bic here. It's a nice rig, but doesn't have a lot of upgradability of headroom.
Core 2 Quad and LGA775 are outdated, they perform okay, on par with Phenom II for the most part but unless you got a deal on them, you're better off with LGA1156 or even AM3. There's no upgradability here. Maybe not a problem, but it just doesn't fell right, at least to me, to buy outdated parts.
Two crap videocards is not better than one good videocard. I guess you get bragging rights, but if bic's numbers are accurate, you could get have got a card that's better than both put together, for less. You could also add another later.
But don't feel bad, it's pretty good compared to the flax I've had to put up with. For years I had an LGA775 motherboard that supported DDR and DDR2, AGP and PCI-e. I didn't have enough money to get a proper all-new rig. It was outfitted with a then-brand-new Core 2 Duo E6300, 1GB of DDR2 RAM, and an All-in-wonder 9800 Pro. It didn't work properly with the AIW, and barely worked at all with its successor, a Radeon HD 4670. It also had a power supply only rated for 230W, and for quite a while a tiny 80GB hard drive. There are limits to how much you should upgrade your PC, and pushing them is a really bad idea.
