When should I upgrade to PCI-Express 2.0?

post #1 of 14
Thread Starter 
I'm currently using a PCI-Express 2.0 video card on a PCI-Express 1.1 slot and I'm planning to upgrade to a 4870. So should I upgrade to a PCI-Express 2.0 mobo or are the performance gains minimal? If so, when should I upgrade?

You will run just fine using a PCI-E 1.1 slot. You won't get a noticeable performace increase from the 2.0 so I wouldn't worry about it for a while.

Hope this helps...

Nah, leave it alone, PCI-E 2.0 is kinda useless, don't upgrade, it's not worth the money.

I'm going to disagree with everyone so far. For a HD48's series, I think you should seriously consider getting a motherboard with a PCI-e 2.0 slot(s). Your current card doesn't max out PCI-e 1.1 though.

The only performance boost you will get is from having a better chipset, thats it

I now have proof (with picture!)

Note that this is with a PCI-e 2.0 slot. Anything under 16x with this game will cut into performance. The results with a HD4850 would probably look closest to this than any other game.

I am using a Gigabyte P35C-DS3R and it apparently has PCI-E 2.0, and I have never noticed any dramatic results vs my old Asus P5N-E motherboard.
