Thanx for the reply Dark Mantis.
I was thinking of getting the NVIIA GTX550Ti graphics card, im hoping my system would be ok to support that card. I was lead to believe the 12v rails on my PSU were separated 4 rails.
I will also likely purchase Windows 7 & install the 64bit version during the price drop as windows 8 is coming.
Once again thankyou for the reply.
