What best socket A I can expect to find?

[Alrik]

Mate of mine is running a Sempron 2600 Socket A Is a Athlon XP 3200+ Barton best I can expect? If so will it make much difference to games when paired with his current 6800GT? Thanks for any help

Tried suggesting a new up-to-date machine numerous times but he didn't care, but he insisted on keeping his current one and upgrading it little by little. I knew they would be expensive but that why I was asking since he says he only get around 30-40 frames in WoW. I knew there wouldn't be much of a difference but just thought it better to ask since he thinks I don't know what I'm talking about :/.

Spec'd him one for around £400 with:
AMD 64 3200+ Was gonna OC it
Asrock mobo
1 Gb memory
500W PSU
7600GT

He would rather spend more then £400 by spending only £100 a time on his current machine rather then all at once on a new build. Tried tons of times showing him all sorts of benchmarks between Athlon XP, Athlon 64 and P4, but in the end I just gave up since he wasn't bothered.

Don't mean no offense but he wont upgrade. He had £200 to spend and he spent on a 1gb memory from 256mb and a 6800gt from a Ati X700 which wiped out his budget. Stopped him complaining about how crap his Pc is, but I just wanted to check if upgrading from a sempron to a Barton was worth it incase he complained about it again. If he was willing to upgrade to the current generation I wouldn't have a problem since I know what I'm looking at but old Socket A I got no clue since I got no experience with them.

And thanks everyone for the info about the barton etc
