i swore you said you had some first gen i7 system. maybe confusing people with goat avatars.
You should upgrade now, don't wait on haswell. Well, not that I can say one way or the other, but no one can tell you if haswell will be good. Most people generally think you should just not bother with waiting. You never know how haswell will turn out, but even if it meets expectations, that's 10% performance increase, as intel says. I mean people said wait for bulldozer and piledriver and look how that turned out. People said wait for ivy bridge, and while IB is pretty awesome (especially dat memory controller), if you had an SB it wasn't worth upgrading to.
I didnt' say rendering, he did.
i do 3d and 2d design on furnture gardens and any thing else i can think of
Sorry I dont know much about this. Do you do this on your current system? How well does your current system handle it? What programs do you use, what program, what program, what program.
If you want a cpu that you can chuck any game at and 'not struggle' then a Pentium G860 would be more than enough power. Maybe an Athlon II, or a Phenom II X4 if you want to make sure to have quadcore for multithreaded applications. Games aren't really cpu bottlenecked, and the ones that are, do fine on a Pentium or athlon ii. i5-3570k is the KING of gaming chips, as in it's just top boss, it'll max out every game, and still have way more power than necessary. It's overkill, way overkill, it's just better fps than maybe a few other chips and only in very cpu intensive games that already run smooth on much weaker chips.
So the i7, on top of the i5, it's just not just overkill, but features that games simply dont use. The i7 beats the i5 in gaming because it has 2mb larger L3 cache, which basically means it runs about 100-200mhz faster. Ie, it's such a meaningless extra, the i7 doesnt beat the i5 because of the hyper threading. i7 also runs 200mhz faster at stock so that's why benchmarks show the i7 beating the i5 sometimes.
Really, you might be best with a pentium or i3. Or phenom ii x4, I really think phenom ii x4 is the way to go for a budget build - with an overclock, it beats the i3 in value since you can't overclock an i3 (even with bclk overclock i think you can max it at like 3.5ghz i think, because stock multi is so low?), that'd also cover your multi-threaded applications.
Then the rest of your money, you put in a GTX 7870. Get it?
My point is that you are basically asking about gaming CPU, and the i7 is not a gaming Cpu, it's an entry level server chip or professional work chip. Like.... a mustang is a fast car. A bugatti veyron? Unless you run the drag strip or whatever, the bugatti veyron is going to be limited to the same 80mph on a highway. I guess that's a bad example but like both the veyron and the mustang are going to drive around the backroads at like 50mph and rev up similarly in the hands of most drivers. If you want gaming power, you go for the GPU, not CPU.
And what games are you even running? It really depends on what you play. Like said, what programs do you use, what programs do you use, what programs do you use. It all depends what programs you use but drawing couches and some games is not i7 territory. You need to realize that all of this chips are insanely powerful, relatively. The pentium g2120 is sold as a high end CPU, because it is.
