I have had a thought... Scrap the entire plan! My current system specs are: MSI K9A2 CF AMD Athlon 5600+ Dual Core 2.6GHz GeCube Radeon 3870 512MB 4GB (4x1GB) OCZ DDR2 (Speed I think is 667 or 800) Monitor is Samsung SyncMaster793DF. Would I be able to play most modern games at good settings etc if I was just to get a 6870, and a decent monitor? Or is my build falling behind now..?
