Compare any two graphics cards:
Radeon HD 7870 vs Radeon HD 7950 3GB
IntroThe Radeon HD 7870 features a clock speed of 1000 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 ROPs.Compare those specifications to the Radeon HD 7950 3GB, which has a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It features 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7950 3GB is 56% quicker than the Radeon HD 7870 in general, due to its higher data rate. (explain)
Texel RateThe Radeon HD 7950 3GB will be a little bit (about 12%) more effective at texture filtering than the Radeon HD 7870. (explain)
Pixel RateThe Radeon HD 7870 is a lot (approximately 25%) better at FSAA than the Radeon HD 7950 3GB, and should be capable of handling higher resolutions more effectively. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Alright, so I have a single 1080p display. I want the better video card to max out any games with. I'm not really that interested in AA but I'd sure like to max it out. I'm ready to pay up anything for any build/model of those 2 cards (DD, GHz etc).
Thanks a lot in advance!
