I've currently got an AGP 939 mobo with a Venice 3500, I'm thinking of upgading to an X1900XT-X but will obviously need a PCIe mobo. I would also be wanting to get a bit more out of my CPU. Which mobos should I be looking at and what am I likely to get out of my CPU, if anything? Is it worth getting an SLi ready mobo as I'm not likely to use this? But there seem to be a lot more features on an SLi ready mobo than on a standard NF4 one.
I haven't got any real budget issues, but less than £400 would be good.
Any feedback would be greatly appreciated.
