dude you have a FX5200 which is a low end card from the FX series. its got a clock speed of 250mhz, i think thats enoguh to run the game on low mode 640x480. maybe not even.
you cant expect your 5 year old machine to play these high end games like crysis and pes2008. games these days are graphics intensive and require better machines. people demand better graphics every year! so the developers give it to them, as a result you will need a new video card which will be able to play it (6600gt, 8600gt etc)
if you're looking for a AGP card, your best bet is the 7600gs, thats probably the best card you can find on AGP platform. i dont believe they made 7600gt's in agp format but if you find one, good luck. 7800gt's were released on agp but you'd be looking to spend a lot more than 60 quid on it.
my 2x 7600gt in sli
runs pes2008 at 1280x1024 high settings with good 40-50fps.
single 7600gt
runs pes2008 at 1280x1024 high settings with less fps but still playable, need to turn down the lod settings.
my 6600gt AGP 550/1150mhz
runs pes2008 at 1280x1024 medium or 1024x768 high.
i havent tested on my 22" widescreens (natural 1680x1050) but so far it doesnt look promising. only the sli 7600gt's would do.
