I've pretty much decided on the following mobo, graphics card, and ram but I can't make up my mind about the cpu. I'm using the build for video encoding. I'm looking for the CPU that's won't create a bottleneck for the system and won't be overkill.

Open Box: MSI 870A-G54 AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

GIGABYTE GV-R485OC-1GH Radeon HD 4850 1GB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL

The three CPU's I'm interested in are

AMD Phenom II X6 1055T Thuban 2.8GHz 6 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Six-Core Desktop Processor HDT55TFBGRBOX

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM3 125W Quad-Core Processor

AMD Athlon II X4 635 Propus 2.9GHz 4 x 512KB L2 Cache Socket AM3 95W Quad-Core Desktop Processor ADX635WFGIBOX

Be 100% sure that your encoding software/apps take advantage of GPU acceleration 1st. If they dun it's easy as pie :p

Thanks guys, you've both given me a lot to think on.

I've got a case, psu, os, & hd already. I was hoping to spend $450 for the remaining bits.

The encoding software I use now seems to use all 4 cores of my Q6600. I'm not sure about 6 cores tho.

I'm building a new machine because my son needs a new computer. I'm gonna keep the new build for myself & give him my old machine.

OK, you've talked me out of the open box mobo. I misunderstood the warranty policy.

With the gigabyte 880 mobo & the sapphire video card, would the choke point be a 955 Phenom quad?

I had kinds set an upper limit of $475. The 105ST will put me into the $530 range after rebates. However if the 955 is the choke point I can rationalize it to the spouse.
