Been waiting weeks for a geforce 6800gt and still i can cancel my order if needed but i just wondered would this kind of gc bottleneck on my amd athlon 2400xp (2ghz) processer? I have 512mb of ram which ive told would help if i upgraded that to 1gig and i could overclock the processer to 2.4 or 2.6 if needed tho if these things arent needed i wont do them if u get me. Any ideas if this gc is a good idea or should i get sumthing lower down the line?

many thanks for the advice in advance peeps

No, your CPU will most likely be the bottleneck

I have an Althon 64 3.2 and I still think that apart from hi(1600x1200) resolution and FSAA levels the cpu is still the bottle neck

You know this forum does have a search function, that's probably why you're not getting replies: This question has been answered many times before. :)

In fact i myself had an athlon xp 2400+ and 512MB of PC2100 ram when i got my 6800GT, so have a search and you'll find the answers i was given. I really don't want to put a downer on your new card, but when i upgraded on that system from a ti4200 to a 6800GT i found that where i got low frame rates before with the ti4200, in games like doom3 and far cry, i got exactly the same low framerates on my 6800GT.

However, it wasn't all bad, where i got mediocre fps with the ti4200 before, i got excellent fps with the 6800GT, and i could run AF and AA at very high settings in most games.

So to put it briefly, in the latest generation of games, your lowest fps will get around as bad as with your old card on that cpu/motherboard combination, but your average and max fps will be better, and you'll be able to run high levels of AA and AF with little impact. In older games (< 2004 release) you'll get consistently good frame rates. So really it just depends on what you play and how cpu intensive those games are.

I upgraded to an A64 3000+ with a 200mhz fsb and that took care of the occasionally severe bottlenecking i had with my axp 2400+.

The cpu/mobo/ram upgrade boosted my timedemo at 1600x1200 in doom3 by over 20fps, and the minimum fps by about 20 also.

i think ill get a new mobo and processer when i can then what would u reommend is the cheapest but will give me the max out of this card, as in processer?

thanks again

I didn't mean to make it sound so bad, i still got about 10500 3dmark03 with the axp 2400+ if i only ran the first 4 tests (no cpu tests). But it is true about the lowest fps in doom3/farcry. For an upgrade most people would recommend an athlon64 for value, however then you're into the whole socket754 versus socket939 debate, i'd google for more info about that. Personally i'm very happy with the performance of my GT on my s754 a64 3000+ with a Gigabyte K8NS (non-pro, about 40-50 cheaper, only difference is the number of HD ports really), and 2 x 512MB kit of corsair value select ram (overlclocks to at least 225mhz from default 200mhz). all in that cost me about 275, i'm not sure what that is in dollars, but about the cost of another 6800GT.

Maybe some other people could chip in at this point with their recommendations? i'm really not an authority on the best upgrade deals, so i hope some other folk offer their opinions too. :)

A CPU upgrade at this point all depends on how long you intend to keep the machine. If you want to do another upgrade in a year or so, I have no qualms recommending the cheaper Socket 754 Athlon 64. But if you want something that will be with you for the long haul, you might have to bite the bullet and get a Socket 939 setup.

Probably the best value going right now is the Socket 754 paired with a 3200+ CPU. You should be able to get both of those and keep your RAM, hard drives, optical drives and whatnot and be out the door for significantly less than $300. The Chaintech VNF3-250 board is one of the most solid values in a S754 board right now - it can be had for $85 or less - it's a solid, no frills setup.

His current rig is an athlon 2400+ though, which at least with mine, was a 133mhz fsb part, so i'm guessing the ram is only PC2100, what ram is it iii? I don't mean to nitpick saturnotaku :) Just i'm sure you'll agree running an A64 with pc2100 ram at 133fsb is going to seriously hamper the CPU's abilities.

He only said he had 1 GB of RAM, he never mentioned the speed of it. It could very well be some DDR400. But you are right, if it's not, then a RAM upgrade would be in order as well.

its 512 ram i will have to check what kind tho but yes i am aware that will need upgrading too :)

p.s many thanks for the help guys gonna get one then get a new mobo processer and finally new ram :)

you have a 3.2ghz athlon64?

technically according to the pr rating he does. the model number is 3200
