This will be a pretty embarassing post (blast from the past) but it has to be asked...
Currently I have a very, very outdated system:
Socket A Sempron 2600+ @ 1.83ghz
1.5gb ddr 333 ram
Sapphire HD 4650 1024mb (AGP, yes I know i know)
blah blah all the other stuff 500w psu and cheapo asrock motherboard....
Basically as you can tell I've been a bit rusty with the whole scene and I've only recently got back into things...
Anyway....I try to play some games on this system and it's ok, obviuosly i don't mind playing games on low or medium. I play Battlefield 2, Half life 2, UT2004....and yes I've even tried playing UT3...without success obviously. So, question...Would it be worthwhile spending £20-35 on an AMD Athlon 3200xp (second hand of course lol)? I'm guessing that my cpu will be the bottleneck. I realise that the FSB would be limited to 333mhz or am i wrong in saying this? Just wondering whether it would be worthwhile because upgrading mobo, cpu, pci-e graphics and ram is NOT an option. I'm a student and have about £50 to spend, and all i want to do is play BF2 smoothly and UT3 on low settings smoothly!
Thanks guys in advance for answers, and please no jokes about my system lol!
Check you buy a 3000+ / 3200+ that does not require DDR400 tho - there is an XP3000+ and 3200+ that runs the 333 / 166 RAM that you have now.
Alternatively look for a 2500+ Barton and overclock it ... RAM speed could be an issue though, and DDR1 is getting expensive now.
From wiki - the Bartons have a 512K cache and are a tad better at gaming due to it.

Get a second hand one (your choice) for a few bucks and it will give you a bit of a boost but a complete system rebuild is required for tackling the latest games at a decent res.
I have a 2400+ running a 6800Ultra AGP and it runs most of the games at low res - running it at 2Ghz - it isn't a Barton.
Going from 1.8 to 2.2Ghz should show an appreciable gain - with the double sized cache from a Barton chip about another 10% gain too.
If your strapped for cash and can get something for a few bucks it will help.
Just don't expect miracles.
An aftermarket cooler will help greatly as these chips ran damned hot - 80 watts there abouts under load.
Don't waste any more money beyond this - try to overclock the one you have for a lark perhaps?
