Hey guys, I need help choosing a computer!!!! I want a Mid-level gaming computer, that is under $840 dollars (before tax) I dont want this computer to have a "alienware computer" like design. Important: I do NOT want to build my own computer, I want to stick with well-known brands (Hp,Dell,Lenovo,Toshiba,etc.) No Sony, Samsung, and whatever. I also want intel not Amd. My main concern is the Graphics card. USES: Mostly playing games like Flight Simulator X, along with regular comfortable use. So I want it to not have weird compatibility issues. I want to run Flight Sim. on Ultra High quality or like high, on mid resolution. REMEMBER: My main concern is the Graphics card. Anyway, these are the specs I came up with. Also, I have the option of a GeForce G310, and a GeForce GT 220. I am almost sure that GTS 240 is better, but just comment to make me sure. $829.00 MAKE AND MODEL: Dell Studio XPS 8100 OS: Windows 7 Home Premium 64-bit CPU/Processor: Intel® Core™ i5-650 processor(4MB Cache, 3.20GHz) RAM/Memory: 4GB Dual Channel DDR3 SDRAM at 1333MHz - 4 DIMMs Graphics Card: nVidia GeForce GTS240 1024MB GDDR3 Hard Drive: 500GB - 7200RPM, SATA 3.0Gb/s, 16MB Cache Disk drive or whatever its called: 16X DVD+/-RW Drive Guys, I cannot afford to upgrade another dollar. Please, keep in mind that I will not be like playing Call of Duty Modern Warfare 2 on maximum settings while downloading a large file from the internet. This is my maximum budget. I would like to stick with a Quad Core CPU. AND I want it to be a Core i CPU. Please help me.
