Vista need's a lot of ironing out.
And for anyone that thinks buying pc components from ebay rathe rthen a shop is a good idea, please be advised that you will need to look at RETURNS and WARRANTY documentation.
If your e-bay seller does not accept a refund, you are more then fucked with a D.O.A (Dead On Arrival) part. At least with Ebuyer, Aria, Redstore, Scan, Dabs etc, etc you have a RMA procedure
