ok can any1 please tell me which si better from the following-
please note that i hav an AGP slot ...

geforce 7600GT 256 RAM VS geforce 6800 XT 512 RAM

geforce 7600 GT VS geforce 7600 XT VS geforce 7600 GS VS geforce
if som1 can rank them (on the basis of performance NOT pricing) then it d b great
please forgive my ignorance ... i m just a layman

also i got intel 865 GBF n i dont intend to replace it just for a pci slot .. so can i know which wud b the best card for me? considering that i hav an ancient 865 GBF

....i ll most likely buy geforce 7600 GT 256 MB or geforce 7600 GT 512 MB... but lemme know if higher cards will cause me any problem

All things considered, you probably should settle for the least expensive AGP X850PRO you can find and only get a faster card, if it ends up being cheaper than the X850Pro.

It would help if you provided more info about your system...like what card you currently have & your power supply specs.

Anyhow, of the cards you listed, here they are in order of performance from best to worst:

7600GT
7600GS
7600XT
6800XT

The amount of memory (256MB vs 512MB) isn't as important as the type of memory (GDDR2 vs GDDR3), plus there are several other factors to consider (GPU clock speed, memory clock speed, memory interface, pixel pipeline, etc)

You might wanna take the time to read this 3-part graphics guide:

Graphics Guide Part 3

thanks i m still going thru the graphics guide n seems that memeory bandwidth is the most significant aspect...
now between 6800 GT & 7600 GT ..which is better?

please ignore this question...

"between 6800 GT & 7600 GT ..which is better?"

i got the answer while surfing .. its 7600 GT

The 7600GT is faster, but I've been comparing cards here:

and it seems like an ATI X850XT is faster than both the 7600GT and 6800GT. I'm not sure how easily you will find one though.

You still haven't listed your power supply specs. Higher end AGP cards require a direct plug-in to supplement their power needs. If your PSU isn't up to the task, you'll have to upgrade that as well.

We'd need to know the make/model of the PSU, the total wattage & amperages on the +3.3v, +5v, & +12v rails

Go with the BFG 6800GS OC. You can get it at Tiger Direct for $130. It is 256bit has 256MB GDDR3 memory and puts out 32GB sec.

It's the best AGP bang for your buck right now. It plays all new games without a hitch.

I'm really impressed with this card but as jam said you may need a new power supply. I've been running it on 300w 15 amp +12volt rail and have no problems... yet.

thanku all for replying ... well i have decided to go on with a total upgrade n buying a PCI E card, something in the 7 series, probably a 7900 card

This is wat was on the PSU
its a LANCER PSU model LC-B350ATX
& i found this on the sticker

DC==o/p

under the heading 115/230 V-
+3.3V == 28A
+5V == 35A

8/4A-
+12V == 16A
-12V == 0.8A

60/50 Hz
-5V == 0.3A
+5VSB == 2A

max 200W for +3.3 & +5 VDC OUTPUT COMBINATION
max 330W for +3.3,+5 & +12 VDC OUTPUT COMBINATION
max 350W for TOTAL COMBINATION

will i hav 2 change the psu too?

Yup!

It's got to go. And that's not just because of its low wattage. There are some 350W PSUs that are much better than their counterpart 500W lightweight junk, as PSU are literally better - the heavier they come. Fact is, in most cases the bigger power supplies are actually designed better, and tend to be more efficient and quieter than the often generic el-cheapos.

Not that I am suggesting one to you, but if you see a reputably branded (dual or more +12v railed) 550W that's SLI-certified, and has an efficiency rating of at least 80% - it should dissipate less energy as heat, and that my friend is a good sign. Should it also come with a large, 120mm or 140mm, dual-ball bearing fan - even better. As this moves more air, at a lower speed, thus producing less noise, something that's mostly disregarded until very late.

There are other things like the ATX12V compliance, the MBTF, PFC and of course warranty. All this makes buying a PSU not so small a decision and definitely not a component you want to cut corners on, but it is not as complicated as it seems either. So if you have applicable questions, feel free to ask.

Lastly, if you think you won't need 550W right now, not to worry, the PSU won’t be putting out all 550W every minute it is on. For the most part, it will only supply slightly more power than the demand from your installed components.

You never did say what video card you have now, but regardless, you're looking at a hefty chunk of change for a complete rebuild. Here's some rough numbers for a Core 2 Duo system:

Board = $150
CPU = $180
RAM = $200
Video = $200
PSU = $90

So figure at least $800 if you want something decent
