On paper, yes - it's got 240 shader's instead of 128, and the GT200 design is more efficient than G80, too. In practice, in scenarios where you aren't running out of VRAM it'll be significantly faster. In scenarios where you are running out of VRAM... it'll choke a bit. But it'll still be faster.

can any of you comfort me :D with saying a GTX275 will sufice

although it's a newer card that has 896mb, that's "only" 128mb more than my 8800gtx :oops:

so will that give a noticable performance boost over my 8800gtx none the less?

thx

memory ain't the one and only thing which makes the gfx card performance

it's quite the contrary in fact, one just need enough memory so that the game won't run out of it, then any additional amount is totally unnecessary

the main thing is the GPU itself and its speed, check out the reviews if you're still not convinced ;)

I'm still wondering where that 2nd post was regarding your which brand GTX275 I should buy is. I was going to reply but the one thread I saw was locked.

Anyway, if you can wait until Oct, getting an EVGA GTX275 might leave you the possibility of upgrading to a GTX300 series DX11 GPU within their 90 day upgrade program window. The Dx 11 cards are supposed to be out Jan 2010.

allright people i have another tech question for you

i read on another forum that i would need a true 64bit OS in order for the gtx 275 1792mb to run at full potential

is this true or not?
i have a 32bit xp now, but could upgrade if need be

headaches included, installing evrything from scratch :?

if you use a 32bit OS it can only address 3GB ram (talking about vista and XP here).

so the graphics card memory would take 1792 of the 3064 (or whatever it is)... leaving you like 1.3GB of ram. plus the page file.

so if i have 4 gig in my system
using xp 32 bit, games are played with only 3 gig?

best thing is to upgrade to 64bit os and the gtx will use all its and system memory?

This is interesting. Partly because it's widely considered 100% accurate... and yet for some reason it isn't always.

I've got 4GB of RAM in an XP system. When I had a 512MB 8800GT installed, maximum available RAM was 3.25GB. I pulled the 8800GT and installed a 1GB Radeon 4850, maximum available RAM 3.25GB. Out of interest, I pulled that card too and stuffed in an old 2MB PCI Rage II card... maximum available RAM 3.25GB. PAE extensions are not enabled.

By the logic of subtracting RAM... I should not be seeing 3.25GB of RAM with the 1GB 4850 installed. It should be at most 3GB, and likely 2.25GB. And yet I am seeing 3.25GB - the same amount as with a 512MB card, or a 2MB card. The system is perfectly stable and happy...

so if i have 4 gig in my system
using xp 32 bit, games are played with only 3 gig?

best thing is to upgrade to 64bit os and the gtx will use all its and system memory?

On paper, a 32-bit OS can only address a maximum of 4GB of memory. That is system RAM and graphics RAM. Conventional wisdom is that running a 32-bit OS with 4GB of RAM means only 3GB is available. Because people were stupid, and couldn't understand this, Microsoft patched Windows Vista 32-bit SP1 to tell people that in 4GB systems there was 4GB installed but only 3GB was 'available'. It saves non-technical people from trying to return the systems they've bought because they "Don't have the right amount of memory" or whatever.

However, Microsoft never went back and did this with XP, so with 4GB of RAM in the system, XP will report anything from 3GB to 3.8GB of available RAM. There is a trick called "physical address extension" that is supposed to fake 48-bit support in a 32-bit OS so that all 4GB of RAM can be addressed separately to the graphics RAM... but it doesn't always work properly and some programs don't like it.

...

If you want to avoid potential headaches... yes, get a 64-bit OS. If you can use XP until October 22nd, or wait until then... you can move to Windows 7 x64.

my GF's system has 4GB ram and a 512MB graphics card,

DXdiag shows 3326MB ram available...

Vista 32bit latest updates

so i guess my above statement is a bit wrong :P
