Is this a good rig?

[EternumSpace]

My rig: AMD FX 4130 3.8 GHZ OC TO 4.3
VTX3D RADEON HD 7770 X EDITION 1GB DDR5
ASROCK 960GM U3S3
A 4X1 GB RAM + 2X1 GB RAM DDR3= 6GB
case AKASA CHIVALRY A-ATX01
750 W PSU.
Is this a good rig for playing games like fc3 lol dota nfs 2012 bad company and gta iv at least on high settings?(dont say that i cannot play on high because i tried these games on intel core 2 duo nvidia 9600gt and 4 gb ram,on high settings and i was playing reaally smoth)

Thank You,EternumSpace

Some advice, don't use mixed ram. Get either a 2x3gb or go for 2x4gb. Mixed ram can mess up you computer quite a bit. Also the 750w psu is overkill, 450w is more than enough. For a video card brand you may want to consider sapphire they are a little more reliable than VTX

Thanks for the advices but i already had a 2gb and i bought 1 4gb so i can boost a little my pc.By saying i would mess up my pc what do you mean?Is this reducing the power of the system?
