Need Help Choosing a HDD for gaming rig

Choice of hard drive won't effect your FPS and has less impact on loading times that you would expect. (Much of the level data is compresssed and you are mostly waiting for the decompression rather than the transfer to complete).

I like drives with 5 year waranty's. Which means a 74-150 WD Raptor, WD Raid Edition, or most any Seagate.

Personally I use a 74 GB Raptor and two mirrored 400GB WD RE2's. But these hard drives were last on my upgrade priority list.

My guess is you will be happy going with a 250 GB Seagate.

Maybe one day you will want to switch to a Raptor, or even two drives in a RAID 0 Config, but changes are you would be better off spend the money on a next Graphics Card instead.

i usually like seagate coz they produce less heat, therefore, longer lifetime

Why not SATA? Samsung 250gb are very good drive.

Your gigabyte motherboard probably has RAID enabled for the SATA connectors. Disable RAID for those and you will only have to plug in the drive to use it. Maybe you'll have to set the jumper for SATA150 instead of SATAII, but the won't cut any performance.
