Need help in choosing mother board

I would look at the ASUS P5P43TD Pro. For this post, Newegg was used purely as an example.

967 + SH – 45 in MIR

I would really look into a AM3 build tho but if you want Intel this is what I would get
GL

above list looks good, if u dont plan to use the pc to game that heavily, u might downgrade the 4890 and choose a quad.

be careful that you match the mb and RAM

DDR3 will not run in most socket 775 mb's . Most will use DDR2

For a E8400, look for a P45 based motherboard from gigabyte, or asus.

Get 4gb of ddr2-800 ram in a 2x2gb configuration.
Cpu performance is not very sensitive to ram speeds.
If you look at real application and game benchmarks(vs. synthetic tests),
you will see negligible difference in performance between the slowest DDR2 and the fastest DDR3 ram.
Perhaps 1-2%. Not worth it to me.
Don't pay extra for faster ram or better timings unless you are a maximum overclocker.

Coolermaster psu is ok, but corsair, PC P&C, Seasonic, and Antec are considered better.

Get an oem cpu cooler with a 120mm fan.
It will keep your cpu running cooler and quieter, particularly if you are running 24/7.

Thanks for the response guys. I'm not keen on DDR3, Intel or AMD. If you guys think i can get better bang for buck with AMD or something else please advise. As far as the games are concerned i would go around 5-6 hrs a day. So please can someone give me a final list of components that i can buy.

^ Well the DDR3 boards and the DDR3 RAM, still have a high price premium attached to them...So I would suggest you stick with AMD and DDR2 as there is not much performance difference going with DDR3 over DDR2...

I would suggest this config...

CPU - X3 720
Mobo - The Biostar boards are cheaper and are of decent quality...
Get any of these boards...

RAM - Going with DDR3 wont increase your performance much...So I would suggest you stick with DDR2...
Should be able to get 4GB DDR2 for about 3.5K( Preferrably Corsair/ OCZ with heatsinks)
Graphics card - Instead of the 9600GT, get the HD 4850 512 DDR3 for about ~7000
And while getting the HDD, get the Seagate 7200.12 and not the 7200.11...
PSU - If you can get a 80+ PSU like the Corsair/ Antec EA series...But for the HD 4850, that CM 500W should be suffice...
Here are few websites, that could help you...

Guys....

Any one else other suggestion left in store. I just to finalize a mobo under $120 which can handle E8400 + 9600GT + 500W COOLER MASTER.I need to build a pc by this weekend.

Thanks guys.
