Radeon HD 7770 1GB GDDR5 Review
Radeon HD 7770 1GB GDDR5 (AKA as Radeon HD 7770 GHz Edition) is a fast-middle-class GPU based on the 28nm GCN (Graphics Core Next) architecture.
It's based on Cape Verde Chip (XT variant) and offers 640 Shader Processing Units, 40 TMUs and 16 ROPs on a 128-bit memory interface of fast GDDR5. The central unit is clocked at 1000MHz while the memory clock operates at 1125MHz. Expect a power consumption of up to 80 Watt.
Benchmarks indicate today's modern games can be played at high settings using a 1080p resolution while some modern demanding games such as Metro 2033 will require reduced resolutions to be played optimally.

First. It HAS 1 GHz, but your card was overclocked, due to power connector. Second. This image is wrong. Write PM to Pip, about adding your GFX.

I don't have a new monitor, but I will have a new 21.5" 1080p one very soon (I was going to buy it the other day, but it din't has HDMI and I want one where I can connect my xbox).
I asked because i can get one very cheap, but it's 16%…

The 7870 requires 500W with 20Amps and the EVGA GTX 660 Superclocked edition requires 450W and 24Amp also the EVGA Superclocked GTX 660 is a tiny bit better. 5% to be precised :P

I think even 7750 will bottleneck… D:
That cpu is too slow to handle these cards
You will be better off getting a 6670 :)
