Powercolor HD3650 Extreme PCS Edition

Introduction, packaging, package and specification

ATI recently released a few lower end cards. We gave you a quick preview of the HD3650, along with some technical info here. Now let's take a longer look at the new card that shows ATI are really trying to dominate the mass-market for GPU's.
With a custom cooler and high clocks, this card from Powercolor looks the part and should perform fairly nicely. Let's take a further look.
Powercolor have gone with the familiar cyber-woman on their packaging for the HD3650.

Inside shows a decent amount of protection for your card, although more could have been put in.

Not a bad go at the packaging then.
The bundle that comes with the HD3650 is a little sparse, but that is to be expected I suppose as this is a lower end card.
You get:

* S-Video to composite lead
* DVI to VGA cable
* Driver CD (not shown)

Not a bad little card at all Kemp, I was very surprised at the performance. It's a pity that it's slightly higher priced because by the time e-tailers add their various profit margins to it the 8600 GT becomes a winner in both performance and price. Regardless, what an insanely cool running card.Quote

I think the market will price it a bit lower after a while. I read in another article that current draw was about 75 watts (quite a bit more than the 8600GT)

I notice the 2 connections for the bridge, I thought how cool to run 3 or 4 of them.


I realize the drivers arent the best now but I just think its so cool to see the 4 cards, not to mention no power pigtails needed either.Quote
