Graphics card can be a tricky bussiness.
But I would say (no offence) that SiS 6236 is one of the worst card out there. It is the 8 MB SDRAM one and from what I've seen my Paramedia 2 based Creative Graphics Blaster Exxtreme at 4 MB SGRAM used to beat it hands down. Also it (SiS) has lotsa compatibility problems. This (GBEx) is one of the sweeetest card I've ever used but is nearly obsolete now.
If you're living in Delhi and are familiar with Nehru Place (and Lemington Road in Bombay I think) you will find TNT2 based 32 MB SDRAM cards very commonly available at less than Rs. 2000. These are the no name, no brand, no support, generic cards. Further they use the obsolete SDRAM memory. And moreover the TNT2 is TNT2 M64 ,which nobody (i.e. no vendor will tell you) and which is not exactly hot
So in a nutshell, I would recommend these,
1.If you are planning to upgrade your processor as well, you may go for a motherboard with integrated video (Intel 810 chipset I think, correct me if I'm wrong). They are pretty decent.
2.If not then, you can go for a NVidia Geforce 2 or TNT2. Don't know much about branded gforce rates in Delhi, but I think the generic one's are available for about Rs. 3000. I would however recommend a branded one, even though the price difference maybe huge. A generic TNT2 M64 32 MB SDRAM costs about Rs. 2000 while its Asus cousin AGP V3800 Magic costs about Rs. 3500 - 4000, but again it performs much better than the generic one.
Take care that:
1. The card is based on the latest DDR SDRAM (comes with a gforce only I think, not TNT2).
2. The card is AGP 4X.
3. It is compatible with your motherboard or else it will be a #### of a nightmare getting it to work. The TNT2 cards are notoriously infamous for this.
4. Prefer a branded card but....... welll if you can' t then you can't no point, go for a generic ddr sdram geforce 2,no less and surely not a generic TNT2..
...hope it helps....
