Sorry for not being able to answer your questions but I also want to get the Palit 2Gb model. How well does the card overclock and will the VRAM allow me to turn up all of the GTA IV settings (draw/detail distance, car density, pedestrian density) on 100?
-- As for the question about Palit cards. Palit if the parent company between Palit and Gainward. And while I could buy Gainward cards here in the states I did. This was back in the Geforce 3, 4 era. But, then for some reason Gainward just went *poof* in the states. Now, I see that they are selling Palit cards in the states. And Palit cards are identical to the Gainward cards. So, they are solid cards. I would buy a Palit card over a MSI,Gigabyte, or Asus. Mainly due to the fact that I'm old school like that and those 3 companies are mobo makers But, I have owned at least 6 Gainward cards through out the years. Never had an issue with any of them. Either on air or water.
++ One BIG advantage for the Palit GTX 460 and 560 cards (768MB,1GB,2GB) is that they ALL use the same PCB design. So, they have the 2.3"(58.4mm) x 2.3"(58.4mm) mounting holes. This allows you to mount up either a pre-09' Swiftech MCW80, or a Danger Den Maze 4 or Maze 5 without any type of mods. And also allows for a great deal of G92 based aftermarket HSF units to be mounted to these cards.
-- The VRM doesn't have a heatsink on it for any of the variations of Palit cards. Even though, I have seen and read about the Palit GTX 460 1GB SONIC having a VRM heatsink. However, I know for a fact that all of the 460 and 560 pcb's have holes for mounting up a heatsink to cover the VRM. And this IS something you want with either a 460 or 560.
I personally was looking at the Palit 460 2GB card, but now for only a few bucks more I can get the Palit 560 2GB card.
I game at 1080p, I know that many say that 2GB isn't needed. However, when the cost is so low between 1GB and 2GB and now between a 460 and 560 with 2GB, I would rather not regret spending the little extra now so that I have 2x the Vram later if I need it. It isn't like we can just buy more modules and stick them onto the card.
Also, CUDA can utilize that 2GB of ram and in theory would be 100X faster when caching larger work loads like working in Photoshop or Premiere. And I know for a fact that the extra 1GB of Vram will help with creating x264 using DVD Fab.
I remember the same thing back in the day with the ATI 9800 Pro 256MB cards. And before that with 64MB vs 128MB. It is always the same story and the bottom line is if you can afford the upper end then get it. It is always better to be safe than sorry, as you never know what is going to come out tomorrow, or what new software is going to do something new that you want to do.
