That video card is shit, go with a GTX 760 or GTX 960. If you are going with an Nvidia card, you should get an Intel CPU. If AMD CPU, then an AMD video card. Also, a 350W PSU sounds a bit low, unless you checked to make sure it was enough, make sure it is at least Gold certified though.
SSD isn't really necessary. And while you can get by with 4 GB (I know I do), I agree, you may want to go with more, at least 8 GB.
SSD's aren't needed but they are extremely useful to have.
Only useful in speeding up boot times and program load times. But that can be helped without spending that much extra money and/or sacrificing disk space by regularly defragging your drives (system files too) with a tool like Smart Defrag, cleaning up junk files, and/or having multiple HDDs with different purposes.
Yeah dude you really should have done your research, no wonder you cant play Graviteam Tactics. You need to get a new video card and return your current PC if you can, you got ripped off. Do not make an impulse buy with a PC, go to the store, tell them the games you want to be able to play etc and work out a build.
Ok this was the original PC I wanted after I did my Research I changed my mind my father had ordered this in mid November
So now if you want to play games you're going to want to get a new video card, SSD card, power supply etc. This can actually be gotten for about 400-500$ and you'd have an excellent game ready pc. The current pc you have isnt made for gaming at all.
