CPU/CPU Bottleneck (help!)

my own custom rig
September 19, 2006 at 07:18:08
Specs: Vista RC1, AMD Athlon 2800+ / 768 MB
Hi all,

I am in need of help. I am currently runnig vista from a Radeon 9200se. From what i undersatnd, this is one of the worst cards round these days (especially in Vista). I've come a long way now and i now know a fair bit about Video/Graphics cards and i am thinking of buying an AGP x800GTO, which brings me to my question...
... what i would like to know is whether my rig [Athlon XP 2800+, 768MB RAM] will bottleneck the x800GTO or vice versa? please help and thanks!
p.s the x800GTO is 256MB & 256bit

The CPU will easily be the bottleneck, you'd have to go back to Quake3 to avoid it!

The 9200SE sucks...it always did & always will.

Before anyone can recommend a video card upgrade, you need to list your system specs. Is your 2800+ a T-bred or Barton? What motherboard/RAM do you have? What about your PSU? High performance AGP cards are very power hungry & have to be connected directly to the PSU to make up for what the AGP slot can't supply. So having an adequate PSU is critical to be able to pull off this upgrade.

What's this obsession everyone's having with Vista anyway? If you plan on running it when it's officially released (whenever that turns out to be), you may wanna hold back on your video card upgrade investment. For one thing, Vista is gonna cost a good buck, especially if you go for the full retail version...you'll be looking at $200 for Vista Home Basic & $400 for Vista Ultimate.

And if you're gonna want the best gaming performance Vista has to offer, you'll need a DX10 compatible video card. I don't know what the plans are for DX10 cards, but I'm guessing that there won't be a huge selection in AGP cards.

Think this thru before throwing down your money....

You should also have at least 1GB for Vista. Maybe 2GB even.

I'd say at least 2gb of ram. I can't imagine playing the newest games on 1gb of ram running Vista that at least needs 512mb of ram to run. Or just stock up on 4gb's of ram if you can afford it, that way you don't have to worry about upgrading for another 2 years. :)

It's unclear at this point if additional memory will be required to run games in Vista over XP.

While Vista itself needs more RAM for basic OS operations due to the architecture of the GUI among other things, gaming possibly may not suffer from this and require more RAM. The reason is the GUI in Vista will be DirectX, not GDI. So while in XP, GDI and Direct3D are both running while gaming, with Vista, only DirectX will be running. (Critics who are gamers however do point out this potential advantage for DirectX games won't be there for OpenGL.) Also, the network stack is completely rewritten to be more efficient.

Any benchmarks right now really don't prove what performance numbers will be like yet since Vista is still not gold.

According to Technet events I've attended, Microsoft reps are saying 1GB is a realistic minimum, but 1.5-2GB would be optimal. More than 2GB would be unnecessary and probably not beneficial for most users, gamers included at least at the time of Vista's release. Obviously, as the patches keep mounting after that, more RAM may be needed later.

I know for sure in the near future i'm going to need 4gbs of ram regardless if i'm running vista or not at that time because Maya keeps on getting more ram hungry with each new version and 2gb of ram is starting to become the minuim.

You shouldent worry about your CPU bottlenecking it too much. I have a Sempron 2600+ the Socket A version, with a 6800 Ultra. My CPU is very much bottlenecking the graphics card but I am still able to play games at high-ish settings. HL2 can play at the highest settings at 1152x864 and constantly stay at or above 32FPS. Every other game like FEAR, Far Cry, GTA SA etc can all play highest settings at 1024x768.

I would reccommend having at least 1GB of RAM but if you can replace a 256MB stick with a 1GB stick you would be better off with 1.5GB

You're in a different boat because you are doing graphics design.

With that said, don't overlook a bottleneck in disk i/o. Everyone seems to know they need RAM, but often don't recognize when there's a disk i/o bottleneck.

What do you still need help with?

brickwood,

You're in a precarious situation. To begin with, the SiS based K7S41GX/GZ is not a good board. And your AXP may be a Barton, but it's a 333FSB Barton. Plus you *only* have 768MB RAM. Your 9200SE is a dog & your 450W PSU *may not* be adequate to handle a high end video card (we'd need to know the brand name & amperage on the +12v).

IMO, you need to think about the long term usefulness of the system in regards to gaming & Vista to decide whether it's worth throwing any more money at it.

That's one of the reasons why I'm waiting for quad core, because the stuff I do for a living I need it.

yeh i think ive come to the conclusion that i need a new rig, but from what i have told u so far, how badly do u think my pc would bottleneck the card (x800GTO AGP)???

--- recap: ---

*AMD Athlon 2800+ Barton
*768 DDR RAM
*Mobo - ASRock K7S41GX (fsb 333MHz/DDR 333)
*450 Watt (generic?) PSU

thanks
