Help me find the right cpu please =]

I was thinking the 3000+ or the 3800+ for 50 bucks more?


Is it worth the preformance increase? How far can the 3800+ be overclocked? the 3000+?



both on am2 socket with a ASUS M2N-SLI Deluxe Socket AM2 NVIDIA nForce 570 SLi mobo


thanks in advance.

Personally, for only fifty dollars....I mean, fifty dollars for a 600Mhz boost? That is about eight cents per mhz. Pretty good, I'd say. Actually it is $55, but whatever. The 3800+ will undoubtley be ABLE to reach higher speeds because it has a multiplier of 12x while the 3000+ only has 9x. To break that down:

We are going to assume that your FSB/HTT maxes out an a wicked 450Mhz; the highest clock for the 3000+ would be 4.05GHz, while the 3800+ highest clock would be 5.4GHz. Now, most chipsets without water cooling have trouble getting to their highest FSB allowed. You want a lower FSB for more "elbow" room. That way you don't stress the memory nor chipset that much, yet still retain an amazing CPU clock.

3800+ is better overall, and the price isn't that much more.

It also depends greatly on the chip that you recieve. You could end up with an awesome 3000 and get it all the way up to 3 gHz (not likely IMO), or you could end up with a crappy 3800 that only goes up to 2.8 gHz (still, this is better than what you would likely get off of the 3000). In terms of the total mHz increase, or % increase, you could acheive, the 3000 is probably the better choice, but no matter how good it is, a mild overclock on the 3800 will still beat it out.

I think this might be over kill for most applications. Yes the 3800 is faster out of the box and has room to over clock but 4-5GHz is a bit on the extreme.

My instinct would be go with the 3800 but do not expect to hit 5GHz right away.

My 3200+ tops around 2.8 GHz on air cooling with nforce 3 mobo.

Well, yeah. It'd be near impossible to hit 4GHz on a AMD without extreme cooling. I'm just saying hypothetically. Here, this is a better situation:

AMD 3000+

FSB/HTT: 215
Memory Clock (No divider): DDR430
CPU Clock: 1.935Ghz

AMD 3800+

FSB/HTT: 215
Memory Clock (No divider): DDR430
CPU Clock:2.580GHz

With the 3800+, you are not pressing the Memory/Chipset yet you achieve a pretty good clock. For the 3000+ to hit that speed, you would have to set the FSB at 286, and I'm sure you'd need a divider (unless you invest in faster, more expensive RAM) which'll then sacrifice some performance and the chipset might not be stable at 286, maybe, I don't know. This is all hypothetical, but should play closely to what numbers you'd get in real life.

if u are investing in a new board and cpu, are u open to an intel chip?

either way all i woudl advise is waiting for the price drops a month from now.

 

[ikjadoon]

I've heard all this stuff about price drops: Is it related to Conroe? How much of a price drop? AMD Single-Cores have dropped already... I'm assuming price drops will be in both AMD and Intle chips...

Yes the price drops are related to the launch of Core 2 Duo (conroe)

it is widely believed (and after seeing numerous benchmarks, i believe it too) that these new intel cpus will be a better bang for buck all round.

the AMD price drops are scheduled for July 24th, the day after Core 2 Duo launches, so i would say wait untill then to decide which u want to buy cause only then we will have complete and comprehensive benchmarks that will give you the best product info. So far Core 2 Duo is outpacing AMD offerings on price and performance, dont take my work for it, do some reading around.

Well, if you can wait, I would. I wish I could, but I need this computer ASAP; it should have already been built and overclocked by this Sunday....I'm going to be late either way, but if I can wait, I shall...

hahah yeah i don't plan on waiting any longer plus i think the 3800+ can hold me off till amd comes out with their K8L conroe killer. My am2 motherboard will be ready =]

 

[ikjadoon]

God, thank you! I need someone to reassure me I'm making the right decision not waiting for Conroe. 'Conroe-Killer' = Nice!

hahaha you my freind are a smart man. I never trusted intel, i think the conroe is going to be good but there is too much hype surrounding it.
