Hi Everybody! I have a question regarding graphics card manufacturers and there differences. I am currently thinking of building a PC and I have been looking into GPU's and got a bit confused............

Here are the basic questions I would like answered... =D

1) What are the differences between the GPU's when it comes to manufacturere? (e.g. MSI, Gigabyte, Sapphire, XFX what changes between the cards?)

2) Taking question 1 into consideration which of the following Radeon 7850 graphics cards would you suggest is better?

-2GB Sapphire Radeon HD 7850 Dual-X, 4800MHz GDDR5, 28nm, GPU 860MHz, 1024 Cores, 2x DL DVI/ HDM/ DP

-2GB MSI R7850 Power Edition 2GD5/OC, 950MHz Core, GDDR5 4800MHz, 2xmini DP/HDMI

http://www.scan.co.uk/products/2gb-msi-r7850-power-edit...

-2GB Gigabyte Radeon HD 7850 Overclocked, 4800MHz GDDR5, 28nm, GPU 975MHz, HDMI/mDP

-2GB MSI Radeon HD 7850 Twin Frozr III OC, 4800MHz GDDR5, 28nm, GPU 900MHz, HDMI/mDP

3) Again referring to the first question, are their any obscure brands to avoid or any major compatibility issues that are known with the different manufacturers?


Thats all my questions for now, to help with the second question, here is a link to my thread discussing the PC components I think i will go for, other than the graphics card that is currently undecided. http://www.tomshardware.co.uk/forum/381531-13-midrange-...

Thanks.

Hi. There are really no differences between the GPUs except for the clock speed, cooler design and overclocking potential. The differences between the brands are the warranty and customer service. All the brands listed in your post are good though I wouldn't go with any of them because you can get the GTX 660 for around the same price here: http://www.novatech.co.uk/products/components/nvidiagef...

Probably slight paranoia, but would it be beneficial to go for a GPU with dual fans to ensure it is cool?

It will stay cool. Dual fans would help in a large(r) case with good cooling. But in a very small case like yours having a cooler design that push hot air everywhere inside the case is probably not ideal. You can see the EVGA allows air to enter through the fan and exit through the end of the card and outside of the case.
