AMD Phenom II x2 with a ATI 5850??

1.) Will the Phenom II x2 555 bottleneck the ATI 5850? I have a sucky build right now and want to play games with maxed settings.

1a) If it will bottleneck, if I unlock another core will that relieve the bottleneck?

2.) I'm also looking for a solid AM3 mobo:

70$ Range:
100$ Range:
150$ Range:

3.) And the Bulldozer will be on the AM3 socket right?

I'm hoping to get nice parts for everything except the CPU. Then when Bulldozer comes around I can grab one, and maybe grab another 5850.

My Current Build:
Dell e510
Pentium D 945 3.4 Ghz
9600GT (OC'ed)
500 Watt Power Supply

What im looking at:
AMD Phenom II x4 555 (Then a Bulldozer)
2-3GB RAM (Will pick another GB or two when i grab a Bulldozer)
ATI Radeon 5850 (Maybe Crossfired later on)
250-500GB (Up to 1TB when i pick a Bulldozer)
500 Watt Power Supply (I might upgrade later...)

1) Yes and No, depends on what games you play really.
1a) of course, basically a (55, it should even handle CPU-intensive games fine.


3) Not really. As of now its set to be on AM3+, which will be compatible with AM3 CPUs but not vice-versa.

Honestly, its a smart idea to grab a a Athlon II X3, a bargain basement AM3 board (like this) invest in a nice cooler (rg. 212+) and fiddle around with OCing. Then grab a HD6870 next week when it comes out. Then when BD comes out, get a nice CPU+Mobo. This way, no incompatibility, and you can change your mind if you cant wait for BD and want to get SB instead.

Thanks for the quick reply! Im not sure what ill be doing any more :lol: , but im going to see what prices look like after the 6850/70 come out.

also id get 2x2xGB of RAM and u will be set for future builds

cuz as it is now most games dont use over 4gb ....ur PSU u will need a better one if u wanna Crossfire....also make sure your PSU is good quality u dont want it frying components.....

a Phenom II X2 can be a bottlekneck but not to 1 5850....maybe if you had 2 5850s then forsure....but the bottleneck of a Phenom II X2 wouldnt be noticeable on a 5850 u should still be able to max out most games....the diff is with it maxes youll have say like 50-60fps whereas some1 with a better cpu will have 80-90fps (which is not noticeable)

Your best bet is to post your budget and what you need there is a stickied topic to follow in the system build section

Don't bargain on unlocking cores; it doesn't always work. Grab an X3 or X4 from the word go.

So an AM3 motherboard would fit a AM2+ or an AM2 CPU?

NO, definitely not. AM3 CPU's will fit in AM2/2+ boards. BUT Socket AM3 has two pins less than AM2/2+, so you cannot put an older CPU in there without breaking two pins off..
