But is it a good gaming rig?

you need a better graphic card, i have the 550ti and it is fine for an i3 cpu. but you wanting a i5 and overclock it, you really can use a lot better.

the 6870 is a lot better.

The 550 Ti isn't really a good choice even with a weaker processor, because you can get more for you money with other cards. Plus most games depend a lot more on the GPU than the CPU, so if you wanted to save money it would be better to get a cheaper CPU and a more expensive graphics card.

Could your rig run GTA 4 with icenhancer at a good FPS?

So is your rig a good gaming rig or do I need to choose different parts?

oh sorry was out . .you mean me?

that rig i posted will do a good job at any game with at least medium to high settings @ 1920x1080 around 40+ fps.

let me look for an actual benchmark for GTA4.

@Sakkura: What kind of CPU would you say is right for me?

Could help you better if you told us your plans for the computer. We know its for gaming but what about OC/SLI?

OC/SLI? i'm new to computer hardware so could you explain?

Overclocking (OC) is increasing the speed of your processor/graphics card/memory to increase performance. Since you are new to computer I wouldn't recommend it. If done wrong you can severely damage your computer.

SLI/Crossfire is the use of 2 graphics cards in parallel to increase performance.

I did not plan to overclock or have two cards.

So I guess the thing i'm asking is if there is a good gaming rig under $800

Might be possible to fit a Radeon HD 7850 in that sort of budget. That's one very nice graphics card. Along with an Ivy Bridge i5 processor, that would be quite a gaming beast.

you mean this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

So all this fits on the motherboard correctly?

And don't I need an aftermarket fan?

Yes.

No need for an aftermarket fan since you wont be OCing.

So how will this new rig do with FPS?

http://www.anandtech.com/bench/Product/549?i=371.372.37...

7850 gets 60 fps in BF3 at 1680x1050 in High quality.

You'll be good to go for a few years as long as you don't "need" to be at the absolute maximum settings with max fps in every game.

Are you sure 500w is a good enough power supply for all this stuff?

Yes.

Ibuypower says i need at least a 650w power supply. Should i trust them?

Unless they are talking about SLI, no.

http://www.amd.com/us/products/desktop/graphics/7000/78...

Trust AMD. "500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended"

75W 6-pin PCI Express power connector?

The connector used to power the card from the PSU. It's supplied.

But isn't the CPU gonna take up 75w in addition to the card?

The CPU gets its power from a 4 pin connector.

6 pin for the card.

24 pin for the motherboard.

It's all supplied with the PSU and there's plenty power to go around.

You just blew my mind! As in THANK YOU SO MUCH FOR YOU HELP! I think that i will buy that hardware. I still can't believe that I was going to buy a pre-built PC! Thanks again!

Good luck.

I recommend you watch neweggs videos on building a PC.

Thanks!

500 W power supply will indeed be fine, the 7850 isn't all that power-hungry, and the CPU isn't overclockable (which would make it suck up more juice).

It's a really nice build overall.

Oh, one last thing: You'll need to get a SATA cable since the HDD is a bare drive.

good follow through and nice.

You get 2 SATA cables with the motherboard.

Cool! Thanks!
