Mainly looking to see if the PSU is adequate, the RAM/Mobo are compatible, and that the 775 series works with the GDDR5 on the 4890.

Open to other suggestions.

That power supply is sufficient, the corsair calculator allows for down to a 450 for your setup even overclocked. The CPU doesnt care what type of memory is on the graphics card, the graphics card is one unit and only the GPU cares if its using GDDR5 or GDDR3, the CPU doesnt even know what type of memory is on the card because it doesnt matter.

Quick note... I am building a system too E8500 version for same type of games (post on this fourm)

On NewEgg if you read the reviews some are reporting that on Page 22 of the user manual Giga motherboard will require a 500W PSU to run. I assume therefore you should be fine. My build with an E8500 and either the 250 or 260 will be using a 520 or 650 Corsair. Another thing I read was that there is a min Amp needed for high end cards (260 has this issue 250 does not) +12 Volt current rating of 36 Amp which some 500W PSU's can not perform.

So check this detail as I could be wrong in my reading as I am a first time builder

Good build, fine as is. One thing i might suggest is that even though WoW is only 2 core optimized add ons will usually work off a 3rd and/or 4th core. Not sure if Diablo3 is multi core optimized. You might think about bumping the CPU to a Q9550

and dropping the GPU from a HD4890 to a HD4870 1GB. Use the money saved for the CPU upgrade.

Just an idea.

^ +1 since WoW uses three threads so one to spare for OS, antivirus, etc but if you used the dual core then they would be stressed out a bit more.

Ahh i didn't know that Prox, i was going off a blue post off the forums. All the more reason to upgrade to the Q9550 then.

If WoW is really the main concern then both the 4890 and the Q9550 would be over kill, although WoW was recently optimized to take advantage of more cores the E8400 would be more than capable of handling WoW on it's on although a quad core can help for other actvities and future proofs better since eventually more games will take advantage of it. For WoW an E8400 nd a 4850 would be more than enough to max it out unless you plan on playing other games in the future at high resolution,then your 4890 would be a good pick. As a side note no matter what you do make sure you get a reliable brand of psu and try to sty above 550 watts just to be on the safe side and have all your bases covered.
