my GT430 runs oblivion with settings on high and TOPS at 60fps - using i5-3250K - 8Gb ram . I tried overclocking with EVGA but upping figures by more than 50 I was getting video break-up. I'd like a more up to date video card but cant affford to spend to many UK £s. Wondered if it was worth getting an HD6670 1Gb DDR5 as Amazon is selling at a price I can just about justify to my other half! Input would be appreciated.
