Right now, I have an ASRock 870 Extreme3 AMD 870 AM3 motherboard with 8 GB of RAM. an AMD Phenom II x6 1090T Black Edition Processor, and ASUS ENGTS450 GeForce GTS 450 video card.

I want to upgrade some components on my motherboard and was looking at that eight core AMD FX-8150 processor and I know I'll have to get a motherboard upgrade (AM3+), but I wasn't sure what to get for a video card.

I saw a video on the processor and they talked about a build called the "Scorpius" build.  I noticed that since then, a 7000 series video card has been put out.

So, I wondered if the Scorpius build is better than what I have, if not, is there one that is and if so, what's the estimated cost?

I'm trying to upgrade the most expensive parts on a budget so I can give these other good parts to a buddy of mine who just had a baby and doesn't have the budget to build him a new computer, so I wanted to help him.  After this, I know he'll need a case, RAM, hard drive, and DVD/CD drive.  But those pale in comparison to a motherboard, CPU, and video card.

Thank you in advance.

Actually all you need to do is replace that GTS 450 video card with something with a bit more...kick. Depending on what resolution you play at and your power supply (make and model please) a simple HD 7870 will give worlds of difference.

I gots me a CORSAIR Builder Series CX600 (CMPSU-600CX) 600W ATX12V v2.3 Active PFC Power Supply.  I think I'm a little above the 1020x768.  Can't remember at the moment.

My monitor needs to be upgraded as well.  I wanted to try to find a dual HDMI out card, but they seem pricy.  I would like to not spend $300 on a video card.

Well let's just go with the fact that you will upgrade to a 1920x1080 (1080p) monitor using a REAL DVI or DisplayPort interface instead of HDMI. Go with a HD 7870, it costs about $250, and most ship with both a passive DVI-HDMI and an active DisplayPort to HDMI adapter, and even if they don't for whatever reason the DVI to HDMI ones are cheap (sub $10) and active DisplayPort to HDMI are $20 or less, though if you only will be driving 2 displays you can use passive adapters.
