What can I expect from my new PC?

That should ace most games, if not all bar the daft ones like Metro. For WoW, it actually sounds rather overkill.

I'm not too sure about the PSU though: 500W doesn't seem enough to me. You may also want to consider getting an SSD, prices are good right now.

Have you bought it already? If not get a cheaper CPU and a better GPU. It is a good build but you will have better gaming performance with a better GPU and that i5 3450 is way more than you need for gaming

An HD 7770 only needs a recommended 430w power supply and that assumes a generic junk model. Xigmatek has several 500w models and while they are not a brand I would recommend any of them supply plenty of power for your listed components.

It should be a decent gaming computer. It's what I would call a mid range to upper mid range setup for gaming. The HD 7770 is decent but don't expect to max the newest games at 1920 x 1080 and up. Pretty much any game will be playable though. Some might have to have the eye candy turned down a bit. The CPU is great.

Thanks

Hi sushi1,

I think you should go with 1600MHz RAM as it is the fastest, officially supported RAM speed for the CPU and it won't cost you much too. It won't boost up your performance significantly but why not get the fastest one when it is available for almost the same price.

Get ASUS 24B3ST Optical Drive because it offers 24x speed and supports almost every DVD except Blu-Ray without being expensive and it outperforms any of its competitors whether it be energy-saving, read/write speeds, reliability, etc.

If you can get AMD HD Radeon 6850 for the same price as AMD HD Radeon 7770 is of, then you should go with HD 6850 as it a more powerful card, performs better in most games and most importantly it has a 256-bit memory bandwidth which results in better performance at higher resolutions.

Rest of your build is fine.
