I was looking at seeing if my son's computer can be upgraded in any way to improve his gaming experience. Or, would I need to build/buy new? He's mentioned wanting a new graphics card, but I was hoping to find out if that would be worth while on his system.
Here's what he has:
1.80 gigahertz AMD Athlon 64
128 kilobyte primary memory cache
512 kilobyte secondary memory cache
Unfortunately, there really isn't a lot do be done with a system that old. About the only recommendation I would offer is to look for an old graphics card like a Geforce 6600GT/7600GS. Anything more than that would probably be wasted on that system. Granted, it would provide some improvement in gaming, but not a lot.
If you can find one on the cheap (say no more than $25), then go for it. Otherwise, I'd look into building a new system.
