I have lately been lagging on minecraft, then i got optifine and it got fixed. Though, i don't like how i actually need a mod in order to run minecraft smooth. I have a 7870, i should not be lagging on minecraft. Is there a problem with my card?

PC Specs:

FX-8320 CPU oc to 3.7 ghz

XFX amd radeon 7870

450 gb harddrive

600w power supply

coolermaster hyper 212 evo cpu fan

Sounds like your lag time is due to loading data files from the hard drive. That is most often the biggest bottleneck on a system. You may benefit from an SSD in this situation, or a better hard drive.

I play Tomb Raider 2013, starting with Normal settings then bumping up textures to ultra and detail to high, etc. On my A10-6800K with no dedicated graphics card I'm getting 60fps (vsync) and dropping to 45fps in heavy situations like the shantytown battles. Using an SSD to eliminate the lag, and there is very little lag or stutter in the game. (Of course, I'm OCd to 4.8GHz, and use 2133MHz memory as well, which helps, with the GPU bumped to 1085MHz for playing Tomb Raider, and run it 720p. I don't get those FPS on 1080p.) Minecraft...

How much ram do you have?
I have an FX-6100 at 3.8Ghz, an HD radeon 7870 as well, and 8 GB of ram. I never get below 50 FPS and I normally hover around 300-400 FPS on far distance and max settings, without mods. I know if you dig around in the newest launcher you can change how much RAM Minecraft is permitted to use. Mines at 6GB and everything runs fine unless of course I blow up the world with TNT or something of that sort. The only thing I think it could be is your RAM, and that minecraft isn't able to use all it needs or wants.
What frames did you get before you started lagging, or has it always lagged until you installed optifine?

No, a 7870 paired with the FX-8320 should not be lagging in Minecraft. Are you trying to run it on Windows 98 or Millenium with only 256MB RAM? No, of course you wouldn't do that.

There has to be something else going on here. Are you having issues with any other games?

Its mostly stutter lag, seems like loading chunks.. when i play WarZ (Zombie Apocalypse Game) and go into large cities, i get lag, then when im in the middle of the city, and everything loaded, im not lagging. So i don't know whats going on, i might just trade my card with a 660ti. There might be a problem with my card.

Minecraft isn't near that demanding.

The only times my game stutters or lags is during game saves, which are saved to my HDD and not my SDD. Picked up an 120GB Kingston HyperX SSD for $80 on sale. While most 450GB drives I've seen are 15000rpm SAS drives and perform quite well, they just can't match what an SSD can do unless you put them in an array.
