I am looking to get a new gaming computer and right now i have a Pentium(R) 4 CPU 3.20GHHz with 1 GB of RAM.

I want to know if the Processor i have now is faster or slower than Intel® Core™ 2 E6420 Duo Processor(4MB L2 cache,2.13GHZ,1066FSB) with 2GB Dual Channel DDR2 SDRAM at 800MHz - 2 DIMMs.

Should i be looking for a duo core processor for my new gaming PC?

Are you serious? Yes you should be looking at at least dual core, really quad core for gaming.

According to the CPU charts, the E6420 is about 114% faster, which is about 20 FPS in gaming terms.

Check out this link to Tom's CPU charts. You can compare any processor they tested across many different programs.

http://www23.tomshardware.com/cpu.html

Find your processor and the new E6420 at the top of the chart then select by program. The 2 processors you have selected will have their results show up in RED.

I'm sure there's more than that... and more to come.

Although Oblivion does take advantage of the 2nd core, the performance increase is only about 10% over that of their single core counterparts.

That's because Oblivion is built on top of the GameBryo engine which make it easy to port games from PC to console & vice-versa. Thus, the engine is not optimized to take advantage of the 2nd core.

Civilization IV is also built on top of the GameBryo engine and should be able take advantage of the 2nd core to a slight degree.

You should write a book.

Yes, you should get dual core, and that one is faster

1)Most games aren't CPU bound, but a 3.2ghz pentium will bottleneck most graphics cards
2)Even if games don't take 100% advatage of the 2 cores, the overhead for the drivers will be reduced
3)Dual cores cost less than single core, so why go single???

No not "atleast quad core for gaming" as one guy said. They hardly help at all.


Dual core is a must. I suggest you get the E6750 since its so unbelievably cheap for what you get!!

I agree. The response alone in multitasking with a dual-core even in single-thread apps is enough to go dual. I went from a 3GHz P4 with HT (simulated multi-processor, which you have I'm sure) to a single-core AMD64 3200+. While the AMD was faster for gaming, it was still less responsive in multitasking than my P4 was. So, I went from that to an AMD64 X2 3800+ and it was like night and day even though very little of what I did was multi-threaded.

So yes, dual-core at the very least! You won't gain much, if any benefit from a quad-core unless you're doing like 3D rendering and complex stuff like that ;)

I have an Athlon 4000+ single core with a GTS-640 and 2GB RAM, I can play all the games I have (including BF2142, GRAW2 and C&C3) at 1280x1024 4xAA 8xAF

so whoever said "Quad core is a must for gaming" is talking crap, quad core won't be a requirement even for all settings max for at least 12-18months

If I get 80+fps in BF2142, but my friends dual core E6320 with same graphics card gets 120+fps, what difference does that make to gameplay? **** all. Graphics card will become a bottleneck long long before processor does.

The PC I'm currently building for friends (3 of them) are E2140's overclocked to 3ghz, better performance than a standard E6700 at a fraction of the cost. (Games benchmarking shows the 1mb vs 4mb cache makes very little difference @ higher resolutions with AA and AF to frame rate, it's all about the graphics card)

This is what youll gain by going dual core, faster frames per second, which, depending on your video card, can be used for eyecandy and to still achieve somewhat the same rates, and ANY program, service etc thats running as you games will have no effects on your game, thus freeing up your other cpu to be used exclusively by your game. I switched from a single core to dual and noticed higher framerates (higher clocked cpu as well) and no lags when not gaming also. As cheap as dualcores are now, you really will want one, if not for what Ive mentioned here, for any game/program that takes advantage of a dual core in the future

Incidentally, a 2.13 GHz Core 2 Duo is much faster than a Pentium 4. Than any Pentium 4. So not only would you have a faster CPU, you would have 2 cpu's, each much faster than your old one. and they run cooler. in short, better in every way.

Okay, thank you all for the good info.

If both you and your friend are using the same graphics card, but you get 80 fps and he gets 120, then it sounds like your single core cpu is bottlenecking you. Obviously his core 2 can push that 8800 harder than your Athlon can. I agree that in gaming the difference between 80 and 120 fps is indistinguishable, but if you run anything else in the background, the dual will shine.

Back to the thread, go dual. I have a E6420. Bump the FSB to 333 and you've got an instant E6750 with no voltage bumps.

Unless it's going to be 2 years+ before you upgrade, buy yourself that 6420. You won't be disappointed.
