Hi all,
A while ago I used some old components I had laying around to build myself a HTCP in a Silverstone Grandia GD07, only thing I had to buy was a new GFX for it, which was the Sapphire Radeon HD6450 2GB DDR3 card. The motherboard I am using is my old one, a Gigabyte P35C-DS3R with some DDR2 Memory.
Now though, I recently upgraded my main PC so now have some other items laying around and here is my question.
Would my old GFX, Sapphire Vapor-X Radeon HD 5770 1GB GDDR5 be better then the HD6450 for a HTCP ? If so what motherboard would you recommend me to buy to swap out the GA-P35C-DS3R I am having now, since I pretty sure the 5770 wont work on that old mobo.
I also have a i5 laying around I can use instead of the Intel Core 2 Duo I having in it now.
Actually, reading back what I just typed, my best option might be buying a new mobo and installing the 5770 (or still use the HD6450 since it do say on the package that it has DDR3 or GDDR5 memory
) with some DDR3 memory and the i5 instead of using the old stuff. 
So, what mobo would you experts recommend for a HTCP build ? Or any other suggestions as what to do ??
Thank you for reading this and I be appreciating all comments and suggestions!
PS: Would my old Corsair HX520W be enough to run it all on ?
