This is my first i7 build, before i buy everything i thought it would be a good idea to get your opinions, im very open to any suggestions at all.

cpu:

ram (only 4gb for now, will upgrade asap)
im not too sure about what ram is the best for an i7, but im thinking one of these 2 may be good:

video cards:
2 ati 5750's in crossfire

Also, i want to overclock the i7 to at least 3.2ghz, then maby go up to 4ghz+ later, would liquid cooling be necessary for overclocking to 4ghz+, ive never overclocked before so if i sound like an idiot try not to laugh too much in the comments XD

I'd go for the ASUS P7P55D-E Pro instead for ~ $189.99.

The PATRIOT RAM kit's voltage is rated too high, while the Dominators are overpriced. This kit would be faster than the Dominators due to lower latencies as well as being cheaper for $109.99, saving you $30:

It is currently out of stock but will restock in a few days, on the 5th of July.

As for your card, I'd spend around $30 more to get a single HD 5850 for $294.99.

If you want to overclock then you'll need an aftermarket cooler. I reckon you'd need watercooling if you want to past 4.0 GHz. A cheap cooler is the Cooler Master Hyper 212 Plus (overpriced on newegg, buy from another shop) or if you want heavy duty air cooling, the Thermalright Venomous-X.

I love the 860.....the Dominator Ram is better and I agree spend a few more $$$ and get either 5850 or 5870 !!!!

If this is a gaming machine then save $100 and go for the i5-750 for the SAME gamign clock4clock performance.

Do you REALLY need an i7?

My suggestion is grabbing an i5-750 and invest the money saved on a HD5850/HD5870 instead.

In addition, get the RAM listed below instead. It requires much lower voltage with great CL7 latency, costing much less as well.

Agreed with all the suggestions. The 860's only advantage is Hyperthreading. Too bad games don't benefit from this. All that matters is clock for clock performance and to a lesser extent the amount of physical cores. The i5-750 is equal in both.

Cheaper RAM is indeed a good idea. Faster RAM doesn't offer benefits in real world applications, it only costs you money.

4GHz can be reached quite easily with air cooling. Note that in order to go over 4GHz you have to turn off all power management, meaning that power consumption suddenly spikes while performance hardly increases at all (in games it doesn't increase whatsoever...). So 4GHz is considered the practical upper limit.

This can be reached with a relatively cheap aftermarket cooler like the Cooler Master Hyper 212 or the Scythe Mugen 2/Yasya (the Scythes are extremely silent in addition to being very potent).
