Guys, i have a mobo that has only ONE PCI-E X16 slot, but it runs at x4.

so which is the most powerful graphics card i can get that will fully utilize the capability of the card?

* i ask cause im currently running a shitty 7300 GT... :cry: *

PCI-E 1.0 or 2.0 because a 4x PCI-E 2.0 slot is equivalent to an 8x slot at PCI-E 1.0 speeds and wouldnt bottleneck as bad

A 4670 or 4770 probably wouldn't bottleneck too badly. A 9600GT would work too.

I believe i read somewhere increasing the pcie frequency from 100mhz would help relieve the bottleneck. =]

If the specs you read are correct, then it's PCI-E 2.0 (4X500Gb/s):

http://en.wikipedia.org/wiki/PCI_Express

This is equal to PCI-E 1.0/1.1 at X8.
That would mean any of the cards so far listed should run with no loss of performance.
There's an article on Toms about PCI-E bandwidth use but it's for the older PCI-E 1.0/1.1 spec, I'll try to find and link to it.

Edit, found it!

The 9800GX2 results are quite interesting;)
