What are you planning to do with the computer? This is extremely important to know. If you're gaming, you could easily drop to an i5-750 and probably afford an HD 5970, and definitely afford an HD 5870. Totally didn't notice the name of the thread...
Everything looks alright, except for the WD HDD. Currently, both Samsung Spinpoint F3 and Seagate 7200.12 are better choices. Not only are they faster, quieter, and cooler, they're also cheaper.
That looks like a good build and I'm on the same budget but without an OS and Monitor but if I could stretch, I could try. So without hijacking this thread, is this a good performance PC for gaming? Like high graphic and on screen action gaming?
I'll ditch the WDs and get the Samsung Spinpoints then. Is there any particular reason the i5 750 would be better than the i7 920 for gaming? Or is it just to reduce the cost of that component in order to buy a better GPU? If it makes a difference, I'll also be using Photoshop semi-frequently.
I'm a bit hesitant on switching to that RAM due to the voltage being at the upper limit for the mobo. Would the difference between the CL7 and CL9 RAM be significant?
I believe that the i5 750 has higher minimum framerates, but primarily it is because of the lower price to accomodate a better GPU. And for infrequent use of photoshop it is not worth keeping the i7 920 as the performance difference between them in photoshop is negligible. http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=363...
If you look at this page and look at the game benchmarks ( http://www.tomshardware.co.uk/core-i7-870-1156,review-3... ), it does not show that the Latency has a consistent impact on performance. So I would say that it does not matter that much, altho it is better to get CAS 7 when you can. Personally I wouldn't be worried about it being on the voltage limit. But you can always try setting the other set at CAS 8 in the bios. Of course if you change to Lynnfield then the RAM game changes a bit as you can look at dual channel sets which might turn out to be better.
