I've been thinking about upgrading my 3700+ to a dual core Opteron, but was thinking what would the cheapest C2D upgrade option be for a decent gaming setup to last around a couple of years.
DDR2 Ram prices are rockbottom at the moment, the 4xxx series seem okay-ish but not so clued up about C2D mobos.
It seems a budget of around £150 or more would be the region??
