Regular pci-e and newest cards?

post #1 of 8
Thread Starter 
Since the newest cards coming out are pci-e 2.0, would their performance differ if they were placed on a regular pci-e slot. Just wondering if I need to upgrade my motherboard when I buy a 4870.

ah okay, so it won't really be worth it to upgrade a whole mobo just yet... maybe in a year or two

Yeah, nothing really noticible unless you really really really care about benchmarks.

IIRC A single card doesn't need anything over PCIe 16x 1.x. The gains from PCIe 1.X 16x -> PCI-E 2.0 16x is due to small tweaks. However in multi-card (crossfire 4850) theres a noticable gain from PCI-E 2.0 16x compared to PCI-E 1.x 16x.

Would a 4870x2 in pci-e 1.x be almost the same as in 2.0 or would there be a noticable loss? I know it is one card but it has more than one core, if that makes any difference.

Nah, the cores dont have to use the PCIe bus to "talk" to each other when they are on the same card.
