My suggestion
C2D E6600 ~ 14.5k
ASUS P5B or Gigabyte GA-P965-DS3 ~ 8.5k
2x1Gb DDR2 667Mhz Transcend ~ 10k
Sony 120C ~ 1900
19" TFT (this is your choice) ~ 14k
Hard disk is again your choice, but I'd suggest a Raid 1 setup for higher performance.
I will NOT suggest a DX10 card now, reason?
well firstly most processors available now are not up to the power of 8800, so u will not see any noticable difference from a 7950GT, and secondly, a 7950 will push all the frame rates you require on a 19" screen, you need a more powerful processor and a bigger screen to make use of the power of an 8800, secondly, they are very costly now, with not much DX10 usage now, it makes no sense, better is get a 7950 now and then, sell it and get a 8800 when DX10 apps are out or u planning on getting another, larger screen. That time these cards will be a lot cheaper, especially after R600 cards roll out.
