Hi fellows I could really use some help. I bought a prebuilt Dell XPS 8300 from the Dell website a year or two ago I already want to upgrade the GPU to run ARMA III when it gets released. I want to run it at max if possible in 1920 x 1080. My current system is like this:
Dell XPS 8300
Windows 7 Home Edition 64 bit
i7-2600 at 3.4 GHz (system specs show it currently running at 3.59)
12 GB Ram
Two 500 GB HDD in RAID
1 GB Radeon HD 6770 GPU
Dell factory PSU- specs unknown
Motherboard Dell Product 0Y2MRG, Chipset Intel PCH H67
I know I need a new PSU for a new Graphics card but I am wondering what PSU to get (looking at Tiger direct and newegg) and would a VisionTek Radeon HD 7870 2GB PCI Express 3.0 Graphics Card or VisionTek Radeon HD 7850 2GB PCI Express 3.0 Graphics Card work in my system and run ARMA 3 at max settings? The reason I am torn between these cards is cause I can get them from Dell and make payments plus they aren't too expensive, just torn on which to get and if they would perform well. If neither is good I could get a VisionTek AMD Radeon HD 7950 3GB PCIe Graphics Card from Dell but that's more than I wanna pay unless absolutely needed and maybe overkill?
