Well Ive dismissed the i5-750 as I dont like the motherboards lack of dual 16x full pci lanes, which is why i've started a new thread, since my last was was 955be vs i5-750. I have ramped my budget up to accomadate i7-920 as it was my birthday (which also gives me free next day delivery on ebuyer)

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. Going to buy first things from below tomorrow as I have the free delivery and its a suitable day. I will then have 2 weeks to decide on the other parts.
From Ebuyer: I'm open to alternatives to the mugen 2 and optical drive, (I feel the tx750 is worth the price premium over the earthwatts 750w)

So after all that I have £437.18 (keeping the £150 for graphics card) , I plan to keep £150 for a graphics card, which at worse would be an ati 4890 in a moth at best may be enough to buy dx 11 card when windows 7 launches.

I'm either going with this I7 build

I know its a frighteningly long post but, I've set it out as the sticky showed, the real important part is the stuff i'm ordering tomorrow (it looks alright to me so 'll buy it if there are no replies)

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)

The x16 lanes are the least of your worries, many users here on Tom's tend to downgrade the 1156 chipset due to this issue and the truth is that you will not see a difference (naked eye) once you compare the performance of both. A GTX 295 was compared first using the top x16 slot and later on the x8 slot and the difference was a 7% performance increase.... nothing to get exited about...

Get the i5 750 and you wont regret it... it can even take on the i7 920 and give it a run for its money.... =)

Yea but that is what the overclocking feature is for.... If you use a little bit of common sense you would realize that all you have to do is overclock the card to achieve a 10-15% increase in performance and in the end you are basically running as fast or even faster as the x16 lane.. Some might consider the x8/x8 a bottleneck but with some tweaking you can actually get more or less the same numbers as an x16 lane.... Nothing to get worried about IMO.....

Another option is to buy one heafty GPU like the upcoming 5870 and this way if you wont need a second GPU.... Just a thought....
