ATI X1400 card swap and current driver

My old Dell notebook is a 6400 / E1505 from 2006. It's still alive running XP home and has a Geforce Go 7300 which i'm hoping to swap out for an ATI Mobility X1400 card (Vendor says 256mb but i think 128mb of this will be shared.) I can do this with my mbo. Not expecting miracles but hoping for 15 to 20% improvement.

Anyhow on the install of the new card should I be using the v old Dell drivers less old and better omega (version?) or looking to install this new 11.4 driver?

I play Morrowind Oblivion Thief Gold 2, 3 - Half Life Deus Ex - any similar type game recommendations?

System:
T7400 Core2 Duo 2.16GHz
2GB DDR2 Ram 6676
1280 x 800 native True Life

Really appreciate your advice and would love to hear from people who have or had this card. Will be "operating" in a couple of weeks.

 

I had the go 7300 & it was overclocked 450/450/900 for 4 years when DA:O was out I tried it on that ancient weakling & surprisingly it did work on low graphics & native screen resolution of 1280*800 ... when googling the x1400 I don't think you will get any sort of performance increase you can't get with simply updating your drivers with the latest ones (using modded .inf ofc) & overclocking your go 7300 with nvidia system tools which will only change your 3d clocks and the card will downclock on idle ... the thing which you can't do with the x1400 ... which is I think a legacy card so you won't get any sort of driver support & modding an ATI driver to work with legacy hardware isn't worth it I guess ...

EDIT: the x1400 is on bar with the go 7400 which is a +100 mhz core clocked 7300

But thats just me

 

Thanks - Good to know - so maybe wasting my time?
Was hoping to overclock the X1400 would you say this a non starter?

Have ATI Tools and can ramp up the 7300 from default 350/600 to 450/700 and 500/800 3D Mark 05 going from 1774 to 2111 to 2313but i'm afraid it'll damage components if gaming for an hour or two.

No trouble with Nvidia driver updates.

am intrigued by (using modded .inf ofc) can u spell this out for me slowly?

 

Go to NVIDIA & Laptop News | Latest NVIDIA drivers and related news | laptopvideo2go.com download any Nvidia driver you want & at the same site you will find a modded .inf file ... that is a file that you download & replace in the driver installation folder that will enable you to install a driver on a non supported card ... but no need to worry regarding modded infs or overclocking because as I told you I had & still have my old Fujitsu with the go 7300 running 450/900 for almost 4 years now & still running solid but you should check the max temps and see if they are reasonable for such an old GPU I would say 70~75 max on load also check for artifacts

But I would overclock with Nvidia system tools because it changes only the 3D clocks so the card will downclock to the 2D clocks while idle saving power, not generating heat & protecting the card

I think the upgrade to the x1400 will be severely problematic & the gain will bes minimal or non existent
