Hi there. I'm running an eVGA 8800GTX 768MB card at the moment. It's great. BUT, I'm looking to upgrade. I have a GigaByte 965P DS3P motherboard. It's capable of Crossfire, runs the PCI at x16 and x4. I don't really know what that means, but apparently it makes a difference when choosing a new GPU. SO, I'm figuring the best bang for buck is to get two 4870s and crossfire them. I won't have to buy anything else. BUT, is it worth getting a new motherboard and buying a secondhand 8800GTX for SLi, it would work out roughly the same cost, but be more hassle. Which would run games better? I'm guessing the 4870s would win, right?
"The last one is 16x 4x, this one is the weakest and doesn't perform very good compared to dual 8x or dual 16x,so i won't recommend it for Multi-GPU configuration. Intel P35 and P965 chipsets support Multi-GPU at 16x 4x mode."
"""is it worth getting a new motherboard and buying a secondhand 8800GTX for SLi"""
as a 8800gtx owner i say no! you will still own old tech its better to buy new tech either ati's new cards out now, or wait till the g300 nvidia cards come out in 2-3 months
"""Which would run games better?"""
at the mo. for best graphics and speed combined to furture proof yourself for 2-4 years get the ati 5870 (as im about to as well)
