That's everything i need, i already have all other peripherals and OS (Windows 7 Ultimate 64bit)
My expectations are to be able to play the majority of modern games, on decent to good settings. So my question for you all is- Are there any changes i can make to save some $$ or just more practical modifications. All those things came up to about 920$ before taxes and as you can see all I'm working is 1,000$

Soo! All advice is appreciated.

Totals ≈ $800 USD.

Will those components match the performance or out preform the parts i picked?

I think at least the processor would crush the one you picked.
I suspect that graphics performance would better it too in most situations.
The samsung F3 is quite quick.

Alright, So considered your parts and basically swapped them all in except the CPU and MOBO

For the reason, I would be over budget because i would still need Monitor,Optical drive and case which would put me a little over 1,015 before taxes.

So im working with

Which is only 902 before taxes

So i do have some room to get a better CPU, so do u know any other good ones, but not quite as expensive as the

Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor BX80623I52500K

I was thinking more toward AMD because they are cheaper and still deliver, but Intel is fine aswell if reasonable.
