Hey all. I'm considering a new build to run Battlefield 3 on High, or custom high-ultra.
I've been reading the performance benchmarks for BF3 and from what I can see, very GPU taxing, while all quad cores ran the game comfortably.
CPU is not important for BF3 . Even very light weight units worked well .
And to make matters even weirder the beta ran better and faster on a phenom than on the intel i5 .
That had to be an issue of cpu architecture because the i5 is clearly the better chip in most situations .
Well I would probably go with the Intel 2500k w/the 2 gb 6950 and unlock it to 6970! If it doesn't unlock you will still be playing with a very potent GPU AMD based systems generally have better mobo's for the same $ that intel has. Look at what options you want on a motherboard a pick the one that fits your needs. Most AMD motherboards come filled with quite a few options. The only drawback is that current Bulldozer CPU's don't look like the best upgrade path ATM. This may/may not be a big deal to you, but it's something to consider.
AMD proposed build cost: ~$540 ($140 CPU & $400 GPU)
Intel proposed build cost: ~$510 ($230 CPU & $280 GPU)
Another cheaper option is to drop some of the cost of the AMD CPU build and get the 2 gb 6950 GPU (like mentioned before) and hope you can unlock it (which seems to have a good chance from what I've read). This would be the cheapest option for the performance in BF3 that your probably looking for.
The 2500k is a really good CPU and is hard to beat for the performance, so don't count it out.
