Is this bundle good for budget gaming

it's fine
just not sure that psu is good quality brand

No, why? Crap PSU, outdated motherboard, 4GB RAM. Here's a better deal for roughly same price:

nope, there is 2x ram sticks totaling 8 gb

The Corsair builder (CX) series are Channel-Well built pieces of crap, too - with the exception of the CX430, they are of poor quality.

I recommend either grabbing the CX430 (which is plenty for your system), or stick with seasonic or seasonic-built (PC Power & cooling, XFX, upper-end corsairs). Superflower-built PSU's seem to be good as well.

wow thanks for the reply guys ill follow the parts as suggested

for the psu is this good?

how about this case?

The GS Series is also built by CWT, though is of a bit higher quality than the CX. For around that price, I would recommend XFX Pro Series 450w.

Cases are mostly a matter of personal preference, there are many good cases to choose from and the Thermaltake will do just fine for you.

cheers!

its the vx builder series you mean

I don't think Nicholas Cage & Sean Connery would show up to save your computer, though.
