Opt for a 500 GB per platter drive ..... Seagate 7200.12 or Spinpoint F3
Check out the performance charts and pick whatever 500 GB per platter drive performs best under your usage patterns. The WD Black 2 TB is a good choice but at smaller capacities, you are limited to the Seagate 7200.12 or the Spinpoint F3. The 7200.12 excels in gaming, multimedia and pictures whereas the F3 wins at music and movie maker. See the comparisons here (copy past link in manually, link won't work in forum):
I want a wide-screen monitor so whatever the best resolution i can get without breaking the bank I cant afford to go much higher then 1200 and that's the range of my build atm. But I'm not an idiot so if something is 100 and something better is only 10 bucks more then yea no complaint there.
For a gaming computer, spend your money on the video configuration first.
With your budget, A 5770 or 5850 would be appropriate. Such a card will give you exceptional performance at 1920 x 1200.
In order to drive a card that strong, you only need something like a i5-750. Another interesting option is the 32nm i5-660 @3.33. It is a dual core with hyperthreading. Very few games today can take advantage of more than two cores.
The 1366 platform is great for high multithreaded cpu users, but not needed for gamers. The exception would be FSX and a few other titles. The i9 6 core gulftown will be a $1000 part. Are you prepared for that?
In two years, the sandy bridge 32nm architecture will be out, so today's upgrade path will be obsolete. Get what suits you today.
