I also have two questions: Will a normal CPU fan and heatsink be fine or would you recommend a liquid cooling?

Is the i7 930 much better than the [URL="http://www.newegg.com/Product/Product.aspx?Item=N82E16819103674&cm_re=AMD_Phenom%u2122_II_X4_955_Black_Edition-_-19-103-674-_-Product"]AMD Phenom II x4 955[/URL] in the long run?

With all these parts I'm just about at my spending limit, so if you make a suggestion please don't make it to much more expensive that the current price.

Thanks for your time.

Get 4GB Ram 1156 Motherboard i5-750 and then you can get a 5870

Or get a Phenom II X4 955, cheaper.

Looks like an Alienware.

It is cheaper but will it be better gaming wise in the next few years?

not for gaming
i7s are expensive because of hyperthreading which games won't use, switching to an i5 means you'll save money on the CPU RAM and probably MoBo and you'll lose maybe a handful of frames

Oh that's fine then, I'll see what i can do with the i5.

Regarding the question about ram.
RAM is very difficult to explain, but i'll give it a shot. Basicly the lower the latency timings the faster your ram will be, however usually with a higher Mhz ratio the latency timings will be higher.
In general, the lower the CAS latency, the better. With DDR3 you should perhaps look at getting 1600mhz ram because it's likely to be the most useful to price, but 1333mhz is just fine too.

[RoboJesus]

Thanks for letting me know about the ram.
Can anybody fill me in on the cooling question?

[Big D Duchovny]

You'll be fine with fan cooling. Unless you like to OC like a bitch.
Just get a good cooler, and you can OC pretty good anyway.. WC doesn't do it THAT much better.

If you're overclocking get a heatsink, if you're not interested in overclocking dont bother jsut stay with the stock cooler.

Water cooling is really for overclockers too, but it looks nice. However it is not practical if you wish to move the computer around alot (lans ect). It may split and leak. I find that water cooling is a little expensive atm aswell.

Your call. I prefer having a nice fan heatsink like the coolermaster v8
