^^ change both your procy & PSU. change the proccy at least to a 2.5-2.8Ghz one. dual core, keeping mobo same. & PSU to a Corsair CX400W/FSP Saga II 500W or if possible to a Corsair VX450W.

yup, the gaming performance also depends on the processor...get C2D e7500 @ 5k for good performance..
moreover your psu needs to be changed as sam mentioned..

YUPPP..change your Processor to E8400 0r higher...and RAM to 4 GB DDR2 667..becoz these boards dont support 800 mhz rAM.TRY ATLEAST getting E7500...if you r low in budget

at 5k, a 7500 is way too costly. a DualCore from 6*** series will work fine at 3.*k range.

E8400 will be more than enough. also he can put in 800Mhz ram. will downclock automatically to reqd speed.

its doesn't matter. even if its eco edition, Extreme Power can't take such heavy load. when he change proccy (& end up with more power requirement) the PSU will tax the card.
