Ok well i wanna build my 2nd gamign rig... since my original one for 5 years ago is almost kapoot.
I plan on recycling my 700W PSU and dvd-burner
Everything else will be new.
Want something to last me the next 3-4 years.
Well without knowing your game preference, whether you plan to overclock or not, and what site you prefer for parts I can only give a general build suggestion. That disclaimer out of the way the following build should play most of the newest games decently well and fall right in the middle area of your budget requirementsat about $540.
Can you reuse your old case? If so, I like bigcyco1's build but you could drop the NZXT case and spend the extra $67.98 on upping the GPU to the 7850 or GTX 560 Ti. Also, you can probably sell your old parts on eBay if you split them up and make ~$100-200 depending on what you had. That could help you get the i5 2400.
Well yeah, so since the PSU is out of the way, go for the i5 3450 and a B75 Pro3 or since you may want to overclock, you can go the i5 2500K & Asrock Extreme3 Gen3 Z68 save some money with Sandy Bridge. Or swap the i5 2500K with an i5 3570K.
