Radeon HD 7770 1GB GDDR5 Game Requirement Analysis

Overview
Radeon HD 7770 is a Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.


Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.


GPU
It equips a GPU Codenamed Cape Verde XT which has 10 Compute Units activated and thus offers 640 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit is clocked at 1000MHz.


Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1125MHz.


Power Consumption
With a rated board TDP of 80W, it requires at least a 450W PSU with one available 6-pin connectors.


Performance
Radeon HD 7770 competes with GeForce GTX 650 Ti but its performance was slightly behind it.


System Suggestions
Radeon HD 7770 is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.

Would this be compatible with an h81m-p33 motherboard, and will there be any bottlenecking with an intel pentium g3258 OC'd to 4GHz? Thanks in advance.

I wish to replace my current GPU with this one, and will require a new PSU. Could somebody suggest one that fits a Dell Optiplex 960 case? The components are fitted together quite snugly - not a lot of elbow room in it.

Sorry for late answer :)
Yes your motherboard is fine for this card. How old is your PSU and what brand is it? I'm 99% sure you will be fine but if I were you I would consider radeon 7790 (needs 5W more but works just fine with my 400W PSU) or geforce GTX 750Ti (TDP only 60W)which cost the same and are more powerful

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.

No. Better buy HD 7850 or R9 270 / R7 260X.
