PCI-E gaming performance in a 8x slot

[Spekham2013]

Hello everyone

 

recently i bought a old server for home use. A hp ml350 g5 (specs: 20gb ram and 1 xeon e5410). It has 3 8x pci-e slots that are electrically 4x. If i would buy a 8x to 16x riser and use a graphics card. A cheap one for around $200 at what type of bottleneck would i be looking at. Is it max fps or display quality? and what type of games could it run at 60fps?

 

thanks in advance

x4 would be a performance bottleneck but not by much

you can find a lot of x4 vs x8 vs x16 comparisons on google

you wont be able to use SLI though

I think crossfire allows you to use 4x slots so obviously AMD thinks it's good enough

That's going to be PCIe 2.0 if I'm not mistaken, still I haven't seen much of a difference between 8x and 16x in terms of performance.

A pcie 2.0 x8 won't even bottleneck a titan.

And pcie 2.0 x8 should preform about the same as pcie3.0x4 which you should have an option to set in your bios I know that it does on the hp dl160 g5.

What about 2.0 4x?  I get the feeling that's what OP has
