How is the gaming build? i7 or i5

Hey I'm building a new computer and want to make a relatively powerful gaming computer.

CPU/Motherboard
I can't decide between the i5750 or the i7920.
i7:

mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813188049

i5:

GPU:
Also I do not know which HD 5770 would be best.

Please feel free to suggest other parts. I am trying to keep the build between 1200-1300 including a monitor while getting the most fps out of games. I mainly play World of Warcraft (I know not very graphics intensive) but I also would like to keep the same computer for many years with just simple upgrades.
 
As for your CPU then definately i5 750.
GPU: Pick either 2nd or 3rd card.
Instead of the motherboard you gave us, how about ASUS RAMPAGE III?
You have repeated the same link twice - in PSU and RAM. RAM is totally fine and as for PSU I'd suggest; Corsair TX750W

For you HDD I'd go for Western Digital Caviar Black instead of Seagate

If it's just for gaming, you'll get the best overall rig by going with AMD. The Phenom II 955 has most of the performance of the i5, and you can use the extra to buy a motherboard that can do dual x16 crossfire.

If you've got cash to spend, the i7 is definitely the most powerful one, but if you have to choose between them, personally I'd downgrade to an AMD rig and get a 5850 instead of a 5770.

I would go for i5 750 as there are rumour of intel changing socket for LGA 1366 again...

GPU - I expect HIS would be cooler? or go for XFX for its warranty.

PSU - If you plan to crossfire eventually, get consair 750W PSU
 
Just wondering do you think it is necessary for me to buy a different heatsink for the cpu if I don't overclock it?

Should I overclock it?
 
It will work well but CF HD4850 will and won't give you same performance as single HD5770 in some cases. It depends what you look at. HD4850x2 is stronger in some points than a single HD5770.


Just like all versions of DirectX, it will take developers time to bring software to market that utilizes the directx 11 feature set fully. You will be fine purchasing a dx10.1 card which should last you quite a while - at least until the 2nd gen dx11 cards hit the market.

In addition to requiring GPU's to have the ability to handle more instructions at once, dx11 as I understand it will offer at least three major enhancements over dx10.1.

1. Hardware tessalation.

Simply put, hardware tessalation will allow for greatly increased detail in 3d scenes without the "need" for substantially faster graphics hardware.

2. General Purpose computation on Graphics Processing Unit = GPGPU.

Finally we have an API which will allow our fancy Nvidia or ATI graphics cards to do more than crunch graphics. Think video transcoding on any GPU, hardware based physics on any GPU without the need for CUDA, PHYSX, etc...

Personally, I'd rather have my GPU doing only graphics but thats just me.

3. Greatly improved multi-threading.

Dual and Quad core or more CPU's will finally be getting a workout from games using dx11 - and the idea is that the more cores you have, the better.
 
Won't work with that motherboard. (well, it will, but the second slot is only x4 so it'll lose a lot of performance) The p55 chipset is only capable of a maximum of x8/x8, which should be ok for 5770's, but if you want full x16/x16 you're going to have to switch to a different platform. P55 was not designed with gamers in mind.

I'd still suggest going with AMD. All 790FX motherboards, and a few 790x ones, are capable of x16/x16 operation, and function a bit better in that area anyway. Intel has nothing on Hyper-transport.


As for the GPU itself, DX11 is slated to be the real replacement for DX9, whereas DX10.1 was almost more of an update. It's worth grabbing one of the new cards. They have more features than just DX11, like lower power usage and better GPGPU capabilities.
Also, rather than crossfire two mid-range cards, you're generally much better off just buying one high end one for the same price. This typically gives more initial performance, as well as more room to upgrade.

+1. Just for gaming go with the AMD.
