I'm looking to upgrade my gpu and monitor and maybe swap over from the rc win 7 with a ssd for the os and some games.
I also want to add a blue ray reader/Writer

I use the computer for a lot of different stuff but this upgrade is mainly for playing games.

I just want someone to check over what I've chosen, what do you think? are all these parts ok or is there any better or cheaper parts avaible?
I'm also unsure if my 520W power supply will be enough.

that's already 3 weeks wages so I don't want to spend much more
thanks for any input

I would be careful with any SSD. They are out there and look to be fine but there are issues with the number of times they can be written to. It is a great concept but I personally will wait a little longer.

I hope this helps.

Don't bother with Windows 7 Ultimate. The only real difference is the amount of RAM it can support, but you will have to buy Windows again if you want to upgrade your motherboard.
Windows 7 Home premium supports 16GB of RAM, the same as your motherboard.

Furthermore, it would probably be less expensive just to upgrade your motherboard to one which supports crossfire and use dual Radeon HD 5770s.

Well, there are more differences between Ultimate and Home Premium, but you are correct. Home Premium offers everything a home user would need, leave the other editions for businesses or enterprises that need features like EFS and BitLocker. BTW, the OP cannot use Newegg since they aren't in the U.S.
