All I am using this PC for will be to play CS 1.6, WoW, Eve, Lineage 2 and maybe a bit of warhammer online... currently have a p4 3.0, 1gb ram and a 6600gt, wondering if its worth just upgrading to 2gb ram, a good graphics card (my mobo is pretty poor though, only supports pci-e x1, its a asrock 775dual-880pro) since it runs all these games just fine, also will be upgrading the hard drive, have a IDE drive at the moment but I heard SATA drives give greater performance. Also is the upgrade from x1 pci-e to x16 a huge difference? if not i may consider just upgrading and getting better HDD and ram than with a whole new build.
If its not worth upgrading, i would need new psu,mobo,cpu,ram,graphics card,hdd but for prices around 250quid there aren't that many options!
any help is appreciated!!!
