x8 lanes and a 8800 GT Tags: Graphics Cards Power Graphics Last response: April 26, 2008 9:30 PM in Graphics & Displays Share unhipzero April 24, 2008 9:40:58 PM 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: http://www.dell.com/content/products/productdetails.asp... 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.

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. jaguarskx a c 327 U Graphics card April 25, 2008 6:11:22 AM 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. romulus47plus1 April 25, 2008 8:05:13 AM Not much difference dude outlw6669 a b U Graphics card April 25, 2008 8:29:34 AM Yeah, it should work fine. I would be more worried about the 305W PSU if I where you romulus47plus1 April 25, 2008 10:17:29 AM 305w... You should consider buying a new power supply. unhipzero April 26, 2008 9:06:23 PM 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.... unhipzero April 26, 2008 9:30:31 PM I'm buying a server because its dead cheap - £117.
