I have the chance to get a secondhand HD4870 512mb for £110. I currently have an HD3870(can overclock to 877mhz). I bought it in late November 2007.
I have an overclocked E4300(at 3ghz) in the rig I am going to use it in and an HX520W PSU and 4gb of RAM.
Is it worth the upgrade or should I wait for the newer 40nm cards coming out in the next few months??
The only games I will play this year are some of the COD series, Project Origin, the Bioshock sequel and perhaps Alan Wake if it comes out.
My monitor has a maximum resolution of 1680x1050 although I usually game at 1280x800 or 1440x900 as my monitor has good scaling.
