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?

It looks like you want to do some customization. It's not real hard to assemble a PC. If that interests you, you should check out the homebuilt section, as linked by obsidian. Our members can recommend a build that will far exceed the HP OEM hardware, for the same or less cost.

I see that HP is unavailable at newegg now. If you haven't purchased it yet, I wouldn't. It's not real impressive.
