Is this a good gaming setup?

[Vegetto991]

Here is what I started off with a HP Pavilion M8400F http://www.newegg.com/Product/Product.aspx?Item=N82E16883107656

and now ive upgraded the graphics card to a radeon hd 4890 and the power supply to 700w http://www.newegg.com/Product/Product.aspx?Item=N82E16817341018

and now im going to add these things to my computer too

is this a good setup for gaming?

HAF 922 is a better case for about the same price. The Mobo is used, I wouldnt go that route personally, but thats just my opinion, its a good mobo otherwise.

That's not a good power supply, check the Antec and Corsairs at 750W. You dont want to skimp on PSU...

I would recommend a 5XXX series over a 4890 any day, primarily for DX11 and heat /power (5770 is a great option with crossfire capabilities.)
