I am planning to buy a New Graphics card. but the problem is I am Confused.

I selected Sapphire R9 270x "4GB" Card but now I saw Sapphire Toxic R9 270X "2GB" Graphics Card.the problem is both card pieces are nearly same but VRAm are very different.:??:

then i saw Sapphire R9 280X "3GB" Graphics Card which is more too expansive than R9 270x "4GB" Card... now "4GB" Card(Sapphire R9 270x) is cheap and "3GB" Card(Sapphire R9 280X) is very costly.:??:

now I dont think VRam too much inportant for Cards graphics power.
what are the exact specs which Tells graphics crads performance.

Thank you.
 
Besides the VRAM size and a difference in clock speed, there's nothing to distinguish the two R7 cards. The R9 is considered a step up, hence the higher price. The 4GB R7 has a clock speed of 1020Mhz, whereas the Toxic version has 1100Mhz.

A big mistake that people make is that more VRAM equals better performance; this isn't true. VRAM is primarily for post-processing effects, such as AA, or for gaming at resolutions above 1080p. If you don't fit into this bracket, 2GB will probably do you fine, but as games become more demanding this could be insufficient.

My advice is to buy the 4GB version and overclock it.

I have single Monitor.. i dont know anythng and never use overclock. i just wanna connect card and play in ultra graphics and highest resolution.
Radeon R9 270X Toxic has clock speed 1100Mhz then it means toxic is better card? i feel build quality of r9 270x 2gb toxic is better than r9 270x 4gb card.
