Hi, I am looking to upgrade my almost 4 year old PC. I want to buy only a new graphics card, but I am not sure if my RAM/CPU/PSU will allow it. The configuration of my current PC is (bought in 2005, Motherboard+RAM+GPU upgraded 2007):
-Intel 945GCL
-Intel P4 3.0 GHz (HT enabled)
-1 GB DDR2 667 MHz RAM
-Local PSU (Cabinet + PSU cost = 1400 only)
-80 GB + 160 GB SATA HDDs
-Nvidia 7300 GT 512 MB
-LG 19" LCD display (L192WS, I think) (1440X900 max resolution)
-LG DVD writer
So, is there any way I can get away with just upgrading my graphics card (and maybe the PSU)? Or do I have to add 1 GB more RAM. Or maybe I need a new motherboard. In the worst case scenario, do I need a new processor to take advantage of the improved GPU?
If only GPU upgrade is required, I am considering HD 4850 or GTS 260 or 9800 GTX+. Which one would be the best for me? Is a new PSU required?
If I cannot escape upgrading my CPU, then what is your suggestion? Do I need to upgrade my mobo as well? This will mean an almost complete overhaul of my PC, as a new mobo+DDR3 RAM+CPU+GPU+PSU combination will be needed?
My preference is definitely for a GPU upgrade only. This is a pretty open ended question, so please feel free to answer as you wish. Don't go strictly by my questions
