Need Help with New Gaming System Build budget 500-700

Are you planning on OC'ing?

Having that large a monitor does require a decent video card.

I would not get the PSU you listed. Broadcom is NOT known for high quality PSU's. It is very easy to underestimate how important a good PSU is so it's worth spending a bit more for one.

I think you should get a slightly more powerful CPU. AMD is the right route. Here's what I recommend:

With this system I included a motherboard that will not support crossfire. If that is something you want in the future, let me know and I can recommend something. But based on what you asked, I think this system fits in well.
1. Better PSU
2. Tower with good airflow and high ratings
3. Solid Motherboard
4. POWERFUL CPU
5. Latest ATI video card that should handle your resolution

I would stick with a stock coolers; they're more than adequate for factory settings. I have a Q9550 and I am using a stock cooler.

You would only save money in switching from an AMD quad to another AMD dual. Unfortunatley, AMD dual cores are not very powerful and are considered weak. On the other hand, Intel dual cores are expensive. So going to a dual core really doesn't make too much sense.

AMD's latest quads (especially the one I recommended) are very powerful and have considerable bang for the money.

It would be nice to be future proof, but I'm more worried about the cooling issues with a crossfire setup. I do like the 1066 ram though; what if i run the triple core processor with the 4890?

Is your TV 720 or 1080p?

So what resolution do you use? For 13x7 or 12x7, a single 4770 is plenty.

But both are overkill for that resolution, and it is always better to use a single GPU if possible. A single 4770 would be $120 cheaper.

So heres the build i was considering :

The total comes to $665.38

So is the one 4770 along with the amd 720 going to be enough to run WoW at max settings without any hiccups? I was also thinking about getting a blu-ray drive down the line as well.
