Regarding a few GPUs

[NatSamp]

So, I've been looking at a few GPUs to buy for a new PC build.I am very new at this.

Can someone give me a few parameters to look at while going for a graphics card. What specifications do I have to look for to choose one over the other?
I know VRAM isn't that important unless you're going for higher resolutions and Anti Aliasing or MSAA. But what other factors matter?

I need a few answers on that.

Secondly:
These are the graphics cards I've seen

Zotac Nvidia GTX 760 2 GB GDDR5

MSI Nvidia Geforce GTX 960 2 GB GDDR5

And a few others, but I know almost certainly that GTX 960 is better than a 760, so why would they put them both on the same price bracket? Or am I still being ignorant? So please guide me as to what factors I need to look for.

There is a fair amount of stuff that dictates what cards I recommend.
In short, it comes down mainly to budget and specifications first.
After that, the easiest way is to look at benchmarks for a newer user. Going beyond benchmarks you have to look at specific cooling, overclocking, and how well the fit specs and budget.

Narrowing it down to your specific question. The 960 IS better than a 760, as the names would suggest. The 7xx series is older than the 9xx series, so the 960 replaced the 760. Thus they are in the same price range, though in the states the 760 costs more due to its limited stocks due to no production.

Can you tell me a few advanced parameters that I need to look into before choosing one too?

I found a few more GPUs

MSI Nvidia GTX 970

Asus Nvidia Strix GTX 970

The GPU Clock on the MSI is 7010 MHz and on that of Asus is 1114 MHz.

How does the GPU Clock affect it? Why is there such a huge difference between the two?

Does GPU Clock and Memory Clock need to be higher for a card to perform better?

P.S - Sorry if I'm annoying you with a lot of questions, I'm just new and I'm curious about learning this stuff.

Its why Im here 😀
Firstly, the 970 is a very nice card, I highly recommend it if the system can support it.
Some more things to look at are, like you bring up, clock speeds and Vram speeds, as well as the construction on the PCB (Better OCs)

The MSI has a VRAM speed of 7010MHz, where as you are comparing the Clock Speeds on the ASUS. They do not directly compare to eachother, though both do have Core and VRAM speeds. In general, of two identical cards (In this case 970s) the one with faster clock speeds will have better performance in comparison to the slower. That being said, you can also overclock to raise clock speeds, and certain brands OC better than others.

All and all, I like the MSI gaming 970.

One last question, can you tell me more about how a system could support a certain GPU? Does support depend on the motherboard? Or are there more factors? Can you tell me more about them?

If it is the motherboard, would it work on this? Asus M5A78L-M/USB3 Motherboard It is an AM3+. I'll be using FX8350 on it.

Does the form factor affect it? Like a Micro ATX

 

[Gam3r01]

So long as the motherboard has a PCIeX16 lane, then it can support it.
Power supplies also impact the card, and those can be checked just from looking at specs (IE the 970 draws 180W and requires a certain power connection and so on)
Lastly in compatibility is the processor, this one is a bit harder for newer users. A processor has to be strong enough to keep up with the graphics card, and this knowledge is simply gained through research. In your case, both the motherboard and processor will be enough for a 970.

There is also the matter of making sure it physically fits in the case. They can fit in some mATX and some ATX. That simply comes down to measuring and looking it up. For example, my case supports cards up to 330mm in length, so I know I must find a card under that length.

Thank you so much for your assistance, helped me out a lot.
