1. There are "single" cards that have "dual GPUs" on em, do they use Crossfire/SLI drivers or normal drivers? 2. For instance, which would be better? 2x 6970 in CF? or 1x 6990? 3. I see PCI-E 3.0 on some new Graphics Cards label, are there mobos with 3.0 PCI-E out there yet? and is there a performance difference when using the same card on a PCI-E 2.0 vs PCI-E 3.0 ??? 4. I have 1x radeon 6950 2gb (I sold my second one...) WHAT would be the best GPU upgrade I could do on my system? (look @ my specs please) I'd like to sell my remaining 6950 2gb and get something with a "after market" cooler on it, so I don't deal with the crappy ones that often come with the reference models... they're often very loud... 5. - NVIDIA seems to have better GPUs in general (better driver support too I hear...) - NVIDIA cards go better with intel CPUs and AMD cards go better with AMD CPUs Are these statements true?
