So I don't know if this is the correct subcategory but some of you may know that Walmart online has an I buy power build your own bundle, well I have access to associates discount (10%) so that's saves me some money. I want it to be under $750ish with the discount.
Say here...
NZXT Tempest 410 Elite Desktop Chassis
Intel Core i5-3570K (4 x 3.40GHz) Processor, BYO Bundle
Microsoft Windows 7 Home Premium, 64-Bit Edition
8GB G.Skill Ripjaws
iBUYPOWER 120GB 2.5" SATA Desktop Solid State Drive
AMD Radeon HD 7850 2GB GDDR5 PCI Express 3.0 Graphics Card
24X DVD+/-RW DL Optical Drive
Base price $915 with discount like $820.
I want this computer to run games like BF3 and Skyrim etc. On my PlayStation simulview and maybe an extra monitor. Is this capable?
PS I don't want to build, I am young and don't have the studies etc. I might screw it up and I try to find similar parts on pcpartpicker but it comes out more expensive :/

For a prebuilt, that's about as good as you will do. You are going to want another normal HDD for storage because the 120gb SSD will go FAST.

Thanks for the input. Yes I was going to get a normal HDD later on too.

850 a custom built machine would offer more GPU
