hello, i have a 9800gt that gives a very low fps on crysis, i went to the shop from where i purchased it and they said that you need to change your power supply, currently its 230watt, i was thinking that i should replace my card with another one as mine does not have a six pin supplementary power connector. so my question is that should i change my psu first or should i switch my card first?

your running a 9800gt on a 230W PSU!? not sure how your doing that without it shutting down as soon as you start a game. the 9800gt needs a 450W psu with 24A on the 12v rail (s). change the PSU. you are fortunate that you haven't overstressed the 230W psu and destroyed the rest of the system.

so changing my PSU will solve the problem?

well you need to, but im not sure how you are running a Q8200 system on a 230w PSU to begin with

ok then, i will get it changed today ASAP

by the way, will the greater power also affect the overall speed of my pc?

Get yourself a a minimum 450W PSU from a reputed manufacturer. You're very lucky that your system is still up and running. I recommend this PSU : http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003&Tpk=450VX
