Need Advice - Building a Gaming PC

Hello everyone, I need some advice on what I should do.

I'm on a tight budget of around $600-700, and I'm planning to build a gaming PC.

At first, I decided to go with an i3 3220, paired with a HD 7870, but then it came to me that upgrading a CPU in the future, would be much, much more difficult than simply upgrading a GPU.

So now, I'm planning to go wih an i5 3570, as I heard countless times that this was a beast for gaming, and pairing it with a decent GPU, a GTX 650 Ti, by the looks of it..

So now, I'm just wondering if what I'm doing now is a good idea, than what I was planning to do before..

 

Thanks in advance.

At least go with the i5-3570k. It is a Quad Core and newer games use more Than two cores. So you will be more futureproof by buying the i5-3570k, and it's overclockable. And if you can't afford a GPU when using it. The Intel HD 4000 graphics is good for many older games. Call of Duty (4: Modern Warfare is the best CoD), Half-Life 2, Counter-Strike:Source, The Elder Scrolls: Morrowind and games of that age. So you can game while waiting on your next paycheck to then buy a GPU and a aftermarket cooler. 

Thanks, and yea, I am planning to get an i5, but just the 3570, without the K, as I have no intention of overclocking, as I have no experience with it, plus it would mean I would need a new and better motherboard, with maybe an addition cooler as well.. I really don't have the money to spend.. Other than that, do you believe what I'm doing; spending more on the CPU now, and less on the GPU, and upgrading it later, is the better option to go?

Yeah I would go for that. What is your budget for the GPU?

With everything else set, it would only leave me around $140-160 to spend on the GPU, and a Palit GTX 650 Ti OC fits right in that price range, only sad thing is that I heard the performance isn't that great, but what can you expect from a card of this level, right.

It's a reasonable card. BTW i would reccomend the EVGA vertion of the 650 Ti. It has a good cooler, good support, simple tweaking tools and etc...

I realised EVGA would always be the better choice, their a top notch brand, but I believe from where I'm buying, the EVGA version is around $190-210..

Upgrading a CPU isn't that hard. Yeah, it's not as easy as a graphics card where you just pull it out and plug a new one in, but it's really not that difficult. Especially, since you already have experience with building your own PC. You had to install the CPU in the first place. Just do the same thing, but backwards, to remove it. Then install the new one. 

You'll have a much better gaming experience with a great video card and a decent CPU, than with a decent video card and a great CPU. I think what you were planning before is the better way to go.
