Ok so a friend of mine wants to buy a graphics card, and he wants to no which one is the best buy, price to performance comparison. i dont live in the US, so right now im giving the price in dollars that prevail here and would like to know which is the best buy in terms price to performance comparison, and which is the best buy in terms of performance. if someone could rank the cards in terms of that it would be great, and give any comments u have regarding the price and graphics card.
1: 5750 ATI PCX ICOOLER IV 512MB (128-BITS) DDR5: $140 http://www.hisdigital.com/un/product2-500.shtml
Well I reckon the xfx 5770 is probably the winner of that, it costs a little more than the others but does that little bit more performance. XFX is a good brand, so I'd recommend that over the HIS model (although nothing wrong with that). Second or par I'd put the GTS 450. I recently bought one and it has astonished me. It has MILES of overclock potential, I've read benchmarks where a OC'ed GTS 450 matches a stock 5770 frame for frame. Keeping things at stock though, the 5770 outdoes the GTS 450. I've pushed my card and had amazing results, I would heartily recommend it. While there's nothing wrong with the 5750 (it performs at stock around about the same as the GTS 450 at stock), to me it's only selling point over the other 2 is that it's cheaper. Otherwise, quite "meh".
So I'd rate:
1) Xfx 5770
2) GTS 450
That's in terms of raw performance, other factors come into play such as which particular games your friend wants to play. In certain games the GTS 450 flosses the 5770, and in others it's vice versa. Some people might talk about drivers as a driving force (pun intended) behind their motivation to buy a particular card. In the end you don't really lose with any of them!
Generally, choose option no.3, that's the most powerful card from all above...
But, do you really need OC'ed card? Because the normal version like option no.4 is still good enough to handle most of games at high resolution...
