Cheap Graphics card for arma 2-3?

hi chad
£100 budget decent card such "gigabyte windforce geforce gtx 650 oc 1024mb gddr5 pci-express graphics card "( http://www.aria.co.uk/products/component... ) .. , has impressive specifications including massive 1100mhz core clock , 1gb of gddr5 memory running @ 5000mhz ddr effective
has 384 shader processors ( known cuda cores ) , 128bit memory interface , results in 80gb/sec memory bandwidth pretty decent card @ price point
in terms of performance ( combined current system specs ) able run arma 2 , arma 3 @ medium high detail .. @ 1920x1080 resolution if monitors native resolution lower then expect high detail ...
if prefer amd based card recommend "xfx core edition radeon hd 7770 1024mb gddr5 pci-express graphics card "( http://www.aria.co.uk/products/component... ) .. has 1000mhz core clock , 1gb of gddr5 memory clocked @ 4500mhz ddr effective ... theres 640 stream processors , 128bit memory interface
performance card around same gtx650.... games optimized specific cards... may worth looking on forums , seeing card works best arma series of pc games ... said cant go wrong nvidia based cards gtx650 wiser choice
in regards power both gtx650 , hd7770 require 450w or better psu 650w psu fine .. both cards require 6pin pci-express power connector ... if psu hasnt got 1 of these dont worry since both cards come molex 6pin adapter .....
hope helps chad.. questions let me know
