TriSLI GTX280, dgn 17% factory OC (EVGA cards), dan OC CPU yg cukup 'gokil' khas XS boys -bisa dilihat dari CPU score nya

QuadXFire R700 (dual HD 4870X2) @default clock, dgn speed CPU yg scorenya 15% lebih RENDAH dibanding tes TriSLI di atas

Kesimpulannya ? nVidia akan kehilangan mahkota the fastest VGA card bulan Agustus nanti sptnya, dan yg beli GTX series saat ini, terutama GTX 280, bakal merasakan rugi yg lumayan kalo launch price R700 @549 US$ itu benar.
Perhitungan ekonominya

Ok, so breaking it down, I get a picture rounded out to look something like this (give or take):
GTX 280 = 4850x2 ($649 vs $400)
GTX 280 SLI = 4850x4 = 4870x3 ($1300 vs $800 vs $900)
GTX 280 3-way SLI = 4870x4.....both of which are bottlenecked... ($1950 vs $1200)
GTX 260 >= 4870 ($400 vs $300)
GTX 260 SLI = 4850x3 >= 4870x2 ($800 vs $600 vs $600)
GTX 260 3-way SLI = 4850x4 >= GTX 280 SLI = 4870x3 ($1200 vs $800 vs $1300 vs $900)
Crazy huh?
1. This is not taking into account 'X2' products pricing, which could be greater or less than 2x the single cards. (silakan masukkan angka 549 US$ utk R700)
2. X4 is a rough approx of X4 or 48x0X2x2.
3. 4850 is going to kick ass.

Be careful in spending your money, nVidia boys.
