I recently started looking for parts for a new gaming pc, but I'm having a bit of trouble deciding which gpu and cpu I should use.

I was pretty much set on buying a Radeon HD 4890 1Gb:

(this is an overclocked version, but the normal is sold out and only $5 cheaper)
I was looking to spend about $200 on my gpu, and this fits perfectly. Now with the Radeon HD 5770 I'm having trouble deciding which to buy.

The 5770 is $20 cheaper, but its also slower than the 4890. In most benchmarks the 4890 gets about 20% more fps, but the 5770 is a dx11 card.

I guess I'm wondering if dx11 is worth the drop in perfomance, and if there are any other performance benefits to using the 5770 over the 4890.

For my cpu I was looking at a phenom II x4 955:

Since this computer is going to be almost exclusively a gaming PC, I'm starting to think that 4 cores is a bit overkill. I'm now looking at the Phenom II x2 550 BE:
http://www.newegg.com/Product/Produ...680&cm_re=phenom_II_x2-_-19-103-680-_-Product
If i go with this I can save $65, which could go towards a better gpu (maybe even a 5850).

So for my cpu I'm wondering if I'm going to see a big difference between the phenom II x4 and the phenom II x2 while gaming.

The PII X4 will show some improvements in newer games that support quad cores, but will be slower than the higher-clocked X2 in older games. You could consider the PII X3s for a good compromise, not quite as good as the quads in newer apps, but just as fast as the X2s for old games. They generally fall somewhere in-between in price.

The 5770 vs. the 4890 is a tough call. ATI really needs to make a 5790 or 5830 card to fill in the gap between the 5770 and 5850. The 5770 uses less power and gives off less heat than the 4890, so that's a point in its favor. DX11 looks to give a lot more tangible benefits over DX10 than DX10 did over DX9, with tesselation giving a huge boost in picture quality, though with a big performance hit.

Maybe try and shave where possible to get the 5850?
