OVERCLOCKING: Yes (slight at first; maybe even stock with undervolting, Then ramping up when I feel I need more)

SLI OR CROSSFIRE: Yes but after 1 year or 2 (I plan to keep the system as long as possible which is why I feel dual 16x pci lanes are neccessary)

MONITOR RESOLUTION:1920x1080

ADDITIONAL COMMENTS: Want quieter components if equal or near equal performance.

So after all that I have £437.18 left

I also don't imagine i7 prices to be falling so if that seems the best option, I'll buy asap. (which I'm leaning to at the moment)

I may have to buy something to may mugen 2 fit on i5-750.

As of now i5-750 is even cheaper than 955be but I assume the 790fx is a better board.

So any thoughts or changes or comments please post

I may consider a slight board upgrade, I personally think the msi pro e is possible best board in the line-up in the toms hardware review. For the UK at least.

The boards Ive seen that seem a reasonable upgrade in price are the
asus p6t
msi x58 platinum

However I haven't seen any really bad reviews of the msi pro e SO i may stick with that one anyway.

The pro e doesn't seem to lack many features, but I'm not exactly knowledgeable about motherboards.

So anyone have more thoughts on either upgrading the i7 board or the other builds feel free to comment

edit: the asus rampage I saw was the mATX version at £170 which is £90 less than the atx version so its not an option seeing as my budget is £1100 not £1240

The real question is do you want to spend 75 monetary units extra on the more powerful CPU ( i7 ) or hold it back to make sure you can afford one of the new GPUs and just have a strong processor (i5).

For gaming performance, getting the i5 and a better GPU now is the short term winner. The i7 has the capability to be faster later if you go dual GPUs or ever get into heavy multi-threaded applications. The new DX11 5800s should ship in europe in 8 days (Sept 23rd).

The AMD cpu is slower, more expensive and has no upgrade room. Not a sensible option right now.
