Hello everyone. Can somebody help me. I have an old PC, e7400 intel core duo 2.8ghz, 2 gb ram, 1gb radeon 5450. I can play games like serious sam 3, unreal tournament 3 at medium settings and resolution at 1152x864 without lag.What graphic card should I buy for me to be able to play the games in a better quality and higher resolution. I'm planning to buy radeon 7790. It is suitable for my pc? thanks in advance, sorry for my broken english

my psu is dps-250ab-22 e. I dont know about 12 vol rail. but it is stated in my psu +12V 15A. does that means my psu is 180 watt?

so will it support 7790? if it's not then what graphic card will it support? or do I have to get a new psu. btw thanks for replying
