this seller is selling a cpu gpu and a motherboard and i was wondering if it is worth the money

$502 for cpu gpu and motherboard

if its not can you guys tell me a gaming pc build

that is not really a bargain it is basically regular priced. They are not bad parts though and that Gigabyte HD 7850 is getting hard to find and at a price of $150 that is a pretty good option. What is your budget for the build?

Those parts are usually found around these prices on Amazon and Newegg

CPU= $220-230

GPU=$140-160 (GB HD 7850 and most 7850s are hard to find new however this would be a solid better choice instead http://www.amazon.com/Sapphire-DL-DVI-I-SL-DVI-D-PCI-Express-100354OC-2L/dp/B00A2J4ROE)

MoBo=$130

As I said give a budget and me and others will try to set you up with the best bang for the buck

I don't see a reason to buy those parts from that guy, you save basically nothing, I'd rather buy brand new from the store.

EDIT: http://pcpartpicker.com/p/2Groj here same money, better CPU, better GPU you can change that to R9 270 if you desire both are equal in power.
