when I o'clock a P700 to 1066 or something like that with a GForce2 GTX and I would get 7000+ on 3dmark.

That is incredible! Especially for a card that cannot do the Nature test (Game Test 4). That would be another few thousand right there. From direct-x 7 compliant GPU's such as that GF2 to a DX8 Compliant one, there is such a gain in 3DMark score (for 2k1), but after that it's kind of not important, as there are no tests in 3DM2k1 that it cant do (3DM 03 is another story ).
