So I'm building a system to upgrade from my (much) older one. I'm hoping to spend between $800-1000 Basically so far it looks like this:
Intel Core i5 2500K Processor LGA1155 3.3GHz CPU
Gigabyte GA-Z68XP-D3 1155 Z68 4x DDR3 HDMI GLAN CrossFireX SATA3 mSATA RAID USB3.0 ATX
G Skill 8G(2x4G)DDR3 1600Mhz PC3-12800 CL8(F3-12800CL8D-8GB

Seagate SATA3 2TB Barracuda 64mb Cache
LiteON IHAS324 SATA DVD-RW 24X Black Retail
Antec Nine Hundred Two Ver3.0 Black Gaming Case

I already have a graphics card:
Gigabyte HD5770 1G Super OC GDDR5 PCIE2.0 DVI HDMI

My current system runs on a Corsair HX 520W. Absolutely brilliant and I've never had any issues with it. I'm wondering if I need to upgrade with this system or if its safe to go with my old one? I used an online calculator and it came out at ~400W with dual HD5770 in Xfire (which I may do later). My thoughts for an upgrade would be:

Antec ATX TruePower 750W Blue

Any thoughts? Revision on the system as a whole is welcome too.

Hello Aevista

Your excellent Corsair HX 520W will be fine with your HD 5770 and the new parts and also work well with any single graphics card you'd probably want for a future upgrade, or the 2x HD 5770 option you mentioned.

Your parts selection is looking excellent.
What's the resolution on the monitor you're using?

Hey WR2

Cheers for the prompt reply. I was a bit worried about the system as a whole, given its the first I've made.
In answer to your question, the resolution is 1680x1050.

You can let your gaming results help you decide if you need to upgrade or add a 2nd HD 5770. At 1680x1050 a single card might still get the job done for you.

An aftermarket CPU cooler like this CoolerMaster Hyper 212 is a good idea.
Much easier to install now than add it later when you start overclocking.

Nice system, PSU is fine, but you might want an HD 6870/GTX 560 or so for this year's games.
