Best mobo etc to upgrade gaming system?

I'm not a newbie to computer building, but my last one was a Celeron 300A (run at 450 mhz) in an Abit BH6 with a TNT video card. That system's currently running a Celeron 566 and a Geforce video card. It's getting a little slow for some current games.

I want to upgrade the mobo/cpu/video/memory and keep as many other components as possible. I was thinking about an Athlon XP, probably around a 2100 or whatever the current "sweet spot" is for price/performance. But, I have no idea what mobos are good for gaming systems.

Any advice would be appreciated.

(I did try searching this forum first, but didn't find anything.)

I am currently replacing the motherboard in my "gaming" system. Going from MSI K7T266 Pro to Asus A7N8X Deluxe. Should be up and running by friday (fingers crossed) and will let you know how it goes. Unfortunately, I don't have the $$$ to upgrade CPU, Memory or Video Card at the moment. Until I upgrade CPU and Memory I will be running this system with AMD 1.4GHz, 512MB PC2100 DDR and Gainward GeForce3 w/64MB.

Then will be upgrading to AMD XP2600+ and 1GB PC3500 DDR ASAP. Will let you know how that goes too!

Good luck

Thanks, I'll look into that MB.

I already have at least a 300W PS. Can't remember exactly, because it's been a few years since I upgraded it. It might be more.

What do people think about the MSI boards, such as the KT4 Ultra?
