[madloo08]

whats inside now currently

GIGABYTE GA-B85M-D3H Intel B85 (Socket 1150) Micro-ATX Motherboard

Processor: Intel© Quad Core™ i5-4440 (6M Cache, 3.1GHz)

Coolermaster 500W PSU

Operating System: Windows 8.1

Hard Disk: 1TB

Memory: 8GB DDR3 1333Mhz

considering the 270x or 280x Sapphire Dual-X OC Radeon

Depending on the model # of the power supply Coolermaster makes a lot of junk power supplies. Without knowing that I would think the 280X is pushing it.

a good 600W power supply would be fine. However, unless you are completely strapped why not get a good 750w PSU? It leads you to having more options moving forward.

If you are thinking of upgrading your PSU at all to get a new VC you should consider a GTX 970. It is going to be in the same ballpark money wise and would run on your 500W PSU. In addition, has significantly more power than either of the two previous cards you mentioned.
