probook 645 g1 Need second opinion

[Matthew J Johnson]

So my old gaming laptop is broke and I don't realy game that hard anymore but still play war thunder here and there and i'm on a $100 or less and I got hooked to a HP probook 645 g1 with a AMD A10-5750m 2.5gz and 4gb ddr3 ram I have more sodimms from an old project.  Could this get by on the old gpu mode on war thunder at around 30-40 fps or should I look for something more high end?
