Hi,

I built my pc in 2009 and its time to upgrade. Last year my graphics card(ATI Radeon 4890) basically died and this year my power supply has started to fail. I dont know what the problem is but I can't get power to my pc anymore. My pc spec is :-

ASUS P7P55D LE P55 Socket 1156 8 Channel Audio ATX Motherboard
ATI Radeon HD 4890
Intel Core i5 750 2.66GHz Socket LGA1156 8MB L3 Cache
OCZ Platinum 4GB (2x2GB) DDR3 PC3-10666C7 1333MHz Dual Channel Kit OCZ3P1333LV4GK)
OCZ StealthXStream 700w Silent Power Supply

I hope that Is enough to work from.

I want to put in a new graphics card, power supply and maybe upgrade my Ram to. My issue is I am not sure what Is compatible with my motherboard. I can Upgrade Ram without an issue. Its mainly I don't know which graphics card my system could handle and what power supply to go for. For the case of the power supply I don't know how much Watts is needed. I felt that this pc was power hungry!

Im not a hardcore gamer so I don't need the top spec components but I would like a card powerful enough to play for example the latest assassins creed or total war games...(I have never been able to run total war correctly).

Thanks for your advice,

Tom
