GPU question

so im new to the whole pc gaming scene and was looking at all these graphics card people have suggested in my topic https://teksyndicate.com/forum/build-pc/need-help-building-my-first-gaming-pc-under-900/176204 but dont quite understand the difference. im trying to build a pc just for gaming. i also seen some cards drop in price these past few days

The difference with any video card is in the performance. By performance I mean that you can turn all the eye candy up in the settings while not impacting your frame rates/frames per second.

The higher the frame rates, the more fluid the game will feel. Think of a normal movie, that's about 30fps, now think of Pirates of the Carrabean on Blu-ray, if you've ever seen it displayed in stores. It has a very fluid and fast movement that seems too real.

Now with cheaper/lower end cards, you will not be able to run more graphic intensive games, like Crysis 3, with all the eye candy at max and run at 60+ frames per second (fps). You will have to sacrifice visual fidelity for performance.

On the other end of the spectrum, with more pricey cards/higher end, you can do that, because the cards are more capable, beit more or faster memory, more cores, higher clock speeds and what have you.

Of course there are more variables to consider, but that's the general gist of it.

I hope that helps

so what about these cards by gigabite,sapphire, xfx, msi, evga?

 

So there are two main GPU chip vendors: AMD and Nvidia.

AMD and Nvidia sell/contract/whatever their chips to other companies, who then deal directly with the consumer.  That's why you see so many brands of video cards(as you mentioned, Gigabyte, Sapphire, xFX, MSI, EVGA, etc)

which do you recommend? nvidia or amd? ive been looking at builds lately so this is what i basically am looking to get. i5 4670k, fractal r4 case with window 8gb of corsair v memory, i need help with a gpu and motherboard, and power supply

Both AMD and Nvidia are very good, so if you have specific need for some of their unique features, e.g., (heavy CUDA and openGL workload favoring nvidia), then simply  buy based on which gives the best performance for the money. If you see a 2 similarly priced cards that fit your budget, then look up some benchmarks.

 

For videocards unless you need one of the unique benefits, there is no brand loyalty.

alright i updated my parts list http://pcpartpicker.com/p/3xrwQ need help with motherboard , power supply and case
