Maximum PC

I play a lot of games on Steam like Skyrim, Borderlands 2, and other games like Aion, World of warcraft, Guild wars 2.

Only problem is that my PC isn't working as good as it used to

I'm wanting to build a completely new desktop, I've gotten a tower and power supply picked out, I'm just not sure about the CPU, GPU, motherboard, etc etc

I want something that's pretty powerful for future gaming experiences, and what not.

I dont' have an exact budget yet, but I don't think I can go super expensive like 2000+

If you think I should change power supplies or whatnot, let me know

Tower: http://www.newegg.com/Product/Product.a ... 6811233102
Power Supply: http://www.newegg.com/Product/Product.a ... 6817182076

Its 12 years old, and can't really be upgraded, it's slow as molasses, and I just can't use it for gaming anymore

Do you mind linking to each of that stuff? I'm not really sure what each is

My recommendation...u will have to change the PSU if u want to game on HD7970...

if you are planning on overclocking, just get the 3570K and MSI-Z77A-G45 mobo with the CM hyper 212+...
u can also downgrade the GPU and get the MSI GTX670... u can keep ur current PSU and case as they are good enough for a GTX670 build...

http://pcpartpicker.com/p/CPAq<<< this will let you play most game maxed out
http://pcpartpicker.com/p/CPCn<<< if you dun want to change your PSU then this build will be good enough...can play most games at high-ultra settings...

Can you add an SSD later after everything is built down the road? Say I have my OS on my HDD. To make it run faster I can put it on the SDD but it is hard to move it over from the HDD?
