256mb or 512mb 7900gs? (or 256mb x1950pro)

256mb 7900GS / 450mhz core, 1320mhz memory
- cheap at £110 but bloody ugly :P

512mb 7900GS / 450mhz core, 1320mhz memory
- only £20 more with double the memory.

HIS ATI Radeon X1950 Pro ICEQ 3 TURBO SILENT Heatpipe 256MB GDDR3 TV-Out/Dual DVI
- £130. Silent (so it says) but more importantly directed airflow out the back of the case (Lian Li PC-60).

Am i going to see any performance gain from 512mb?
I play GTR2, Trackmania, maybe Oblivion again and I will be doing some 3d rendering in the near future but im not sure if the gfx card has much to do with that.
Bearing in mind the card I buy will be used for the next year till I upgrade to a DX10 card.

Which would you buy?

  1. The X1950pro defintely. With that HIS cooler on top of it, its a good bang for your buck. Also most likely comes with a factory overclock on it.
  2. the 512mb vs 256mb X1950 PRO made no difference in all of the benches I made for the first AGP review I did on Tom's.

    That was on an older CPU mind you, in the next review it might make a difference.
  3. IMO, the extra memory is really just for "future proofing" as most games don't use that much memory yet, mind you I am currently playing Quake 4 again at Ultra settings and it says when starting the game that it requires 500Mb.

    Google 256 Vs 512 and there are a few reviews and tests regarding this very issue. The 512 only wins out at higher resolutions (1280x1024 min) and higher AA and AF settings (4x and 16x).

    If you are only getting one card I would recommend the X1950, it will easily beat the 7900GS on it's own unless you OC it alot then it evens out.

    My cards look to be the same as the ones you are considering (mine are a Chinese card, Unika and yes they are ugly), if they are they are the same they are built on a 7800GT board with an upgraded power supply circuit, mine OC well to 585/760 and that ugly cooler actually works very well and is not noisy at all.

    I only got the 7900GS because I wanted dual cards and the crossfire solution was way too expensive for me but I am very happy with it's performance.
