What will I be able to run with this...

[paskowitz]

Dell Studio XPS 16
I was able to build all it for just $1265

-Obsidian Black High Gloss Finish
-Intel® Core™ 2 Duo P8700 (3MB cache/2.53GHz/1066Mhz FSB)(should I go to a 2.6 with a 6mb cache +$96)
-Genuine Windows Vista® Home Premium Edition SP1, 64-bit
-Edge-to-Edge FHD Widescreen 15.6 inch WLED LCD (1920x1080) W/2.0 MP
-4GB Dual Channel DDR3 SDRAM at 1067MHz (2 Dimms)
-500GB 7200 RPM SATA Hard Drive
-8X DVD+/- RW(DVD/CD read/write) Slot Load Drive
-ATI Mobility RADEON™ HD 4670 – 1GB
-Intel® 5100 WLAN Wireless-N (1x2) Half Mini Card
-High Definition Audio 2.0
-Dell Wireless 370 Bluetooth Module (2.1+EDR)

So at what levels would I be able to play games like Crysis, Bioshock, Mass Effect, AC, GRiD, etc?

well bioshock, mass effect, ac(assasin's creed?) and grid at max settings but I'm not so sure about crysis

either way, you should be able to play all newer games on high settings with decent fps so no worries

With that resolution, for Crysis you will have to play on medium or possibly low.
