Hello there i want to ask some noob questions i know this already been ask

what is difference between 1gb gpu to 2gb of gpu?

I'm planning to buy a gpu but can't decide which i would go 1 gb or 2 gb btw I'm only using
1 Monitor. they say 2 gb ver. of gpu is for 2 or more monitors only for 1 monitor 2gb is not advisable is that true? that 2 gb gpu is good for 2 or more monitor only?

Does 2gb ver. of gpu make lot difference in 1 monitor rather than 1 gb ver.?

Another question does

#1 i3 4130 bottleneck with Sapphire R9 270 Dual-X Boost 2gb/256bit?
#2 fx 6300 bottleneck with Sapphire R9 270 Dual-X Boost 2gb/256bit?

which i would go? i want to upgrade i3 to i5 but its out of my budget this two have almost same price here in my country like 2 - 3 bucks difference.

First lets get you straitened out on the 1 GB vers. 2 GB. It is not 1 or 2 GB of GPU, it IS 1 or 2 GB of RAM on the GPU. You will use more than 1 GB of RAM on the GPU with a single monitor depending on the games you play. I use 1.8 GB of ram on a single monitor playing some games so go with the 2 GB cards.

Go with the AMD FX 6300 if your only choices are the two you mentioned.
