You see, the 9800GT Sir Ahsan got was most likely (I am 99.5% certain) a defective card. The 9800GT's shader cores cannot be changed, if it is a 9800GT, then it has 112SP - simple as that. Now the only difference I see are with the 9600GT, which XFX even mentions on its site.
The HD4870 has only two versions, the same video card with 512MB and the same with 1GB memory. You will not experience anything like less shader cores with buying the HD4870 - unless it is has a manufacture defective (which is a 0.3% chance? less?).
