x8 lanes and a 8800 GT

[unhipzero]

Hey guys,

I've hit a bit of a dilemma - I've just bought a new server (Power Edge Su440) and I want to purchase a graphics card for it (8800 GT).

PE spec:

I'm worried because the Power Edge's spec reads that it only has a x8 lane PCI-e port with a x16 connector.

Can someone explain and shed some light on it. Should I cancel my order of the Power Edge and buy a normal Desktop?

Thanks,

Ed.

no dont worry x8 is plenty bandwidth for ur card. ur gonna to lose some fps on high needed bandwidth game like flight simulator but not much. I wouldnt let it bother u.

yea, i know tom's has done multiple articles on the subject and found that there is barely any difference between using 8x and 16x. perhaps a few FPS here and there, but it wont be noticeable.

That's because gpus aren't powerful enough yet to saturate the bandwidth of the bus. The exception is if your card runs out of onboard ram and has to use main system memory.

You know, I've read an article that stated you will experience an average of 15% performance drop with a 8800GT in a PCI-e x8 slot.

I could have sworn it was an Anandtech article, but I scrolled through their GPU reviews and I couldn't find it.

Not much difference dude

Yeah, it should work fine.
I would be more worried about the 305W PSU if I where you

305w...
You should consider buying a new power supply.

Hmmm.....interesting so you guys think I should invest in a new PSU. It's going to be hassle to find something which will fit....

I'm buying a server because its dead cheap - £117.

Found a link regarding PSU/gfx issue.

Has anyone tried installing win XP Pro on one of these things?
