Advice on a GPU

Okay, first off I'm a console guy planning on coming over to the PC world.

I was looking for a little advice. I took one of the builds off of one of your YouTube videos and tweaked it a little.

$100 AMD Phenom II X4 965 Black

$143 GIGABYTE GA-990FXA-UD3

$50 2 Mushkin Enhanced Redline 4gb DDR3 1866 SDRAM

$200 Kingston HyperX 3K 240GB SATA III

$278 HIS IceQ Turbo Radeon HD 7870

$110 Antec Nine Hundred Black Steel ATX Mid Tower

$109 CORSAIR Enthusiast Series TX650M 650W

$10 Arctic Silver 5 High-Density Polysynthetic Silver Thermal Compound

That would be my shopping cart, though I'm not too set on the IceQ Radeon.  Anybody have any alternative suggestions that would fit these tweaks better?

Possibly an EVGA Superclocked GeForce GTX 660 Ti?

Why is the 7870 a beast? I was always told go Nvidia or go home. Thanks for the power supply link.  Also, how crucial is it to have a SSD, I don't have any hardcore gaming experience with computers.  Would I be able to dump the SSD completely and go for a 1TB HD?  How much would that affect gameplay?

7870 is a beast. Also, try this power supply and if you dont have already have a hard drive and your downloading and playing lots of games, that ssd wont cut it. you will also need a hard drive

go for a new fx vishera, the phenoms were great in their day, but their just too old. and a 240gb ssd is excessive, 120g is fine. $50 for 4 gigs?!?!?!?!?! get 8, be about $40.

need an aftermarket heat sink regardless. you also need a data drve, i reccomend the WD green or blue

About how much can a 6300 vishera OC to with a cheap aftermarket heatsink and fan similar to a Cooler Master Hyper 212 Plus? A lower memory SSD paired with a HDD would be cost effective... Just put the OS, Steam, and Games on the SSD then?  Also, I was going quality over quantity with the 2 Mushkin 4 gigs.  Isn't 16 gigs of RAM is overkill anyway?

having an 8GB of ram is enough for gaming. 

7870 beats the competeing nvidia card at the same price (gtx 660).While the 660 ti does beat the 7870, if your in that price range go with the 7950. Personally i have an nvidia card (gtx 480) and i kinda of prefer them but at the price point your looking at the 7870 has better performance. Btw anybody who says things like go Nvidia or go home is obviously a fanboy.

Now about SSD's, they dont affect actual gameplay, just load times every now and again, along with boot up times. You can completely ditch the idea of SSD's, but then your boot time will be like 10 seconds slower. Since you were looking $200 240gb SSD. Instead I'd recomend to go with a 120gb SSD and a 1 or 2 TB hard drive. Maybe even a 3 TB hard drive, because its such a great value.

recommending XFX 7870. I really prefer that brand, I damaged my 6950 and they replaced it. As for storage I also agree trash the 240GB SSD unless you plan on only having like 10 games at a time. Grab a WD blue or black 1TB.

CPU, I'm on the intel side, but if you're going to go AMD then yes, jump up to one of the newer FX series chips. Well worth buying newest generation.

Good choice on the PSU btw, although you MAY be able to go a bit lower if you don't plan on adding much more.

Actually if you are new; i highly recommend the arcticles on this site in regards to building a cost effective gaming rig.  Then work your way up in the future as you are more comfortable.

Btw welcome to the PC gaming scene

Go with the new Vishera CPUs, definitely good value for their money and an improvement over bulldozer.

As for the HIS 7870 I believe Logan did a review on one and is pretty fond. I'd reccommend that as well/
