Hi everyone. So I just installed my brand spankin' new, shiny Zotac 8800GT Amp! Edition (700/1700/2000). The only way I could fit it in my case was to put it in a 8x PCIe 1.1 slot, on my eVGA 133-K8-NF41-AX. How much of a speed penalty should I expect to see coming from a eVGA 7800GT OC which was in the 16x slot? (445/1070) How badly will putting the card in a 8x 1.1 slot hurt its performance?
Hi, I am going to be using 2x 3870s in a P5W DH Deluxe and will have the same 8x8 for my cards. I haven't found any info that says "Yes 8x is fine" but every time I look for info everyone says that todays GPUs don't use the full potential of PCI-E 1.1. The way I reason it out is that the HD2900 has the most bandwidth of any card(~105G/s) and at the time they it came out and the Crossfire benchmarks were done the only choice was 8x8 so if they weren't bottlenecked then the 3870(~72G/s) and 8800GT should have no problem.
yeah, it's that my performance is worse with the new card. my connection is great. and yeah, i know my cpu is a bottleneck, but it shouldn't make a better card worse than a worse card, know what i mean? it's baffling.
also, i know WoW isn't a very graphically intense game, but the workload should scale up to the new card's architecture. it there's an issue with the new DX10 architectures not performing optimally under DX9, perhaps i could see a problem, but i don't know of any.
