Hi, This thursday i am looking to buy two products,
The Sapphire ATI Radeon HD 5770 vapor-x 1GB Model
And a Corsair 650TX Power Supply

What i want to know is will the card be compatible and run well with my processor, a
AMD Phenom 8450 Triple Core

All i want to know is how this will go together, please only reply if you know. This is a 380 dollar decision im making. How well might it run basically.

Other Specs
Windows Vista
4gb of Ram

Another note this card will be used to play games like gta 4 and stuff.

No need to upgrade to such a hefty power supply with that card, unless you're planning on running Crossfire in the future? Save yourself some money if you're not..

$380? Just for those two items? Where in the world are you shopping? Both of those can be had in the low $200 range if shopping the US.

Power supply is definitely overkill for that card. This is already more than enough:

Compatibility with CPU is not of concern....compatibility with motherboard is. Make sure your motherboard has a PCI-E slot.

The Phenom 8450 isn't the greatest multi-core processor and will probably hold back the Radeon 5770 a bit in some games.

Especially something like GTAIV, which seems to be very badly optimized even on my 2500k and HD4890.
