P.s can someone explain to me what ivy bridge is
everyone is saying to upgrade to that or i5/i7 and what would be the equivlent to an i5 and i7 in AMD.
Ivy Bridge is a codename for a generation of processors. Like Bulldozer is the code name for the AMD FX series CPUs. Ivy Bridge would be your i5-3450s/3550/3570K, etc. Sandy Bridge was the generation prior to that, i5-2400, 2300, 2500K, etc.
As far as upgrading to an i5/i7. I won't lie to you, thats what you should have done in the first place, but anyone making blanket statements like that quite frankly I wouldn't take advice from. As far as an AMD equivalent, depends. Technically Bulldozer FX-8120/8150 are, but more often than not they fall short of i5 performance. nothing AMD has can really match an i7 however. My Phenom II overclocked to 4.0GHZ is actually better than my i5-2300, but thats because the i5-23xx series have shitty clock speeds.
They didn't bother to find out other information, like the graphics card you're running, or any other potentially relevant information. Nor did they care that you have already spent money on this system and would basically be throwing it in the trash. This is why you don't listen to fanboys lol.
Speaking of relevant information, what is the full specs of this system? If you have a decent motherboard, I'd wait to see what PileDriver (thats the next generation AMD CPU) brings to the table. It might be worthwhile to stick it out with the FX for now, but really, I think you might be happy enough just overclocking the FX-4100 and getting a better video card for now. Its only a few games the FX-4100 really gets its butt whooped, as long as you stay away from those, I think you can still have a couple years of fairly satisfactory computer usage even with the blighted bulldozer.
BTW, get a CPU temp checking program, you should be monitoring your temps for a week or so after a build to make sure everything is Kosher. HWmonitor is a free program, download it.
