You doing that just for fun? You have capable rig with your 6790.


Yes, just for fun. :) I posted some numbers on another thread here, completely forgot about this one. I need to run some actual tests because the numbers I was basing upon were rough numbers. But the 6570 and A6-3650 so far seems to be a good combo!!

People really exaggerate Sandy bridge performance in gaming, here's a Battlefield 3 beta CPU test by http://www.techspot.com/review/448-battlefield-3-beta-performance/page7.html

Hah, something broken in that list. i3-2120 same speed as i5-2500k, oooooookay.

Beta software + beta drivers = meaningless. Go look up various games on the shelves today that are popular to get real numbers. Many of them do just great on PhII / etc, but some don't. SC2 comes to mind.

I ran my 6790 on my Llano, there is no way that it performs as good as my 2500k did. I was getting mega stutters in highly clustered areas where my 2500k did not. As much as I would like AMD to outperform in gaming.. it just doesn't.

Correct me if I am wrong, but doesn't that slide show that BF3 is NOT CPU dependent given that everything is within 10fps?

There could be so many variables to that as well. Im sure the CPU is not at fault but it could be memory, motherboard controllers, drivers etc. I do notice slight hiccups on my Llano but that is expected for a budget CPU running at 2.6ghz.

If you overclock a 2500k and 2600k it will bump the performance results to 53fps and it goes absolutely no higher. There is a bottleneck somewhere else obviously and I am betting its memory related.. I think AMD has a little more memory bandwidth to work with and I bet they are only using the memory at 1333mhz on the Intel setups. ;)

Techspot always has the most screwed up cpu results. they are the only site that will show Sandy Bridge getting beat by a freaking Phenom 2.

BF3 seems to love quads, so if u eventually want to play bf3, i'd get a i5 2500k. but if not a small i3-xxx will be enough for most games.

I'm thinking of just getting a phenom 2 x4 be from microcenter with a free mobo. It's only $119 with a mobo and that's pretty darn cheap. I'm seriously lost now on the video card, its only 1280x720 res, I don't need max AA but I'm sure at this res most video cards will do it.

What do you suggest for a cheap gpu to go with a x4 be chip at this res?

Looking at microcenter I can get a CPU,mobo,RAM and hard drive for about $200. Case,psu,dvd will be another $100 just leaves me my video card and OS left

1280x720 with no AA? Radeon 5770/6770 is probably a good match, or pony up for the 6790 or 6850 for a bit more power - but certainly don't go any higher than a 6850.

Most of the time you get what you pay for regarding performance. So a chip that will cost you 120$ mobo included will perform poor. What Phenom is that? Anyway, I played the BF3 beta on my second machine with a C2D E8400, stock 3GHz and a GTS450 on an LCD TV, native resolution 1368 x 768 and it played well on a combination of low and medium so I'd say a 5770 is a minimum but for 40-50$ more you can get a 6850 which is great for that res.

I'm assuming it's a 955 (3.2GHz, unlocked) which will certainly not perform poor. Doesn't Microcenter give the mobo for free? $119 is the asking price for a 955 these days.

Yeah you get the mobo for free. I figure for $119 that's a steal for the CPU and mobo. Sure the mobo is cheap but the CPU is unlocked so it should just be changing voltage and the multiplier to overclock it.

What about NVIDIA cards? Like a gtx 460? I remember seeing those for around $100 not long ago. At this res I shouldn't need a ton of graphic horsepower since im mainly playing cross platform games right?

I won't be playing Bf3 at all, I can't get into battlefield at all. The games would be like these
Fallout 3 and new Vegas, call of duty, and whatever I can snag dirt cheap on steam LOL

Hyper Threading cannot be compared to real cores. Yes it gives 10-20% boost (On an i7, not sure how much on the i3), but it can't come close to doubling the performance in well threaded applications/games.

But I second the Phenom II route. I got mine for $130 with free shipping. And it may be slower than an i5-2500, but it cost me a whole lot less. I doubt you will be disappointed with it.

Maybe you are right about hypertherading not being as effective as a real core, but just makes AMD look even worse, since 2 hyperthreaded SB cores beat six AMD cores.

The only way the Phenom II is competitive is if you overclock it compared to the i3 2100 or a lower end SB quad that will not overclock much.

Personally, I would go with a Sandy Bridge quad. You can get a 2300 for well less than 200.00.

I am going to be selling my HD5750 soon as I upgrade to something for BF3. It runs every game I have tried at 720P perfectly. I played through the beta of BF3 decently as well, just had most settings at low at 1080P. Not sure what I am going to ask for it. If you are interested, make an offer. Just not 100&#37; sure when I am going to upgrade, really want a 7K series card, but I may settle for a 6950.

EDIT: Oh yeah, its been clocked at 825/1350 with zero issues for some time.

But if you want new, I would think a 6770 would be great for you.

I can't afford to drop $179 on just a CPU, i have to build a whole tower, OS and all. That's the only reason I'm thinking phenom 2 right now. I could always get a sb Pentium 620 for $60 then when i have the extra cash a few months later grab a 2500k

I can understand that, although a SB quad seems more future proof than an AMD quad, both from a performance standpoint and future upgrade path.

My earlier response was directed to the implication that an i3 2100 is not a good gaming cpu because an AMD phenom II has "moar coars", as every AMD fan brings up.
I was just pointing out that despite being only a dual core, the i3 2100 is very competitive in almost every game and sometimes beats the phenom II x4. The only game that seems to favor the phenom II x4 is Battlefield 3, and we wont really know the performance in that game until the final game comes out.

An i3 2100 is a great CPU for things that don't use more than 2 cores. However, most all new games these days make full use of 4 and even 6 cores (BF3, Witcher 2, Crysis 2, etc). The other thing the Phenom II has going for it is over clocking. They are unlocked and easily hit 4GHz (well, current chips do).

However, with an i3 box, you can always upgrade later to a quad like the 2500k/2600k and then blow the doors off a Phenom II. Same goes for the low end Pentium. Get it now, upgrade it later.

Well that link I posted shows a Pentium g620 vs a x4 965 be and at stock clocks the Pentium is hanging nicely. I know its only a dual core but it will be a way for me to get the build done cheap and be on the 1155 platform now. At least on 1155 I've got upgrade options. I don't like building and spending money on pc stuff, ill admit that. I know once I go quad (2500k) I won't upgrade the CPU, mobo, RAM for a couple (3-5) years LOL.
