Hello i've been using my computer quite a while now and this is a question i've been wondering.I have Asus 7950 DCII GPU and AMD FX-8150 CPU with a Motherboard M5A78L-M/USB3.From what i can see my motherboard supports PCI-e 1.0 and my GPU is PCI-e 3.0.I've searched the net and only found 2.0 vs 3.0 and people were saying that only gpus' would bottleneck it would be titan or 7990 with a PCI-e 2.0 mobo but i have 1.0 so how much would it effect my performance if i were to buy 2.0 or 3.0 mobo or would it effect it at all.

Your motherboard supports PCI-e 2.0. Your card should still work fine. It will perform slightly better on a 3.0 board, but it's probably not worth upgrading just for that.

Thanks man since asus website didn't specified it i couldn't understand what was it.Yeah it doesn't worth upgrading just for that i have a ssd so i need SATA III and new chipset 990fx but since i'll be buying a new mobo for SATA III i'll wait for PCI-e 3.0 mobo with AM3+ support.They don't sell the only mobo that is PCI-e 3.0 for AM3+ in my country yet.
