there are various architectural advancement in the diff drams.
the ddr5 that we find these days are better performer than it’s older counterparts…
n u won’t find ddr4 in many cards coz afaik they had lesser cost/performance advantage compared to ddr3…
in a budget around 4k,i’ll suggest u to go for a used card with warranty of course…try searching the market section!
n ya ur smps will pose a little problem for any gcard u choose…
so it’s up to u if u wanna take the risk!
crosfire is a tech used when you use more then 1 graphic card(for ATI | SLI for Nvidia) in a system(could be 2 or 3 or 4 cards).
the 4670 will be streched if you go for a 22" moniter with something like 1680x1050, and you might need to strech your budget a bit for a better card … but it also depends on what type of games you play or what you plan on using the system for … 4670 would be perfect if you are sticking to your 15" moniter…
Well if you go for a better performing card then you have change your PSU as well. So you will have to increase your budget. For anything upto a 19"/20" monitor a HD4670 will do a decent job.
The HD4670 is the best bet in your budget.
better to get that in India ..4670 from newegg works out around 3750 if you go KMD route its gonna cost you even more 4500 approx which is just about same as indian market price …plus you will have not much warrantry troubles if any problem comes.
Err. HD5450 gaming capability is not even as much as the HD4550. The HD4650 is the cheapest card one should consider for gaming and its performance is twice as much as the HD5450.
In his budget a HD4670 is the best option as it has low power consumption and performance equal to and even better than the HD5570 at times.
thanks for your help, but pls confirm if ATI 4670 will be able to handle 22" monitor resolution and will i have to upgrade my PSU for it and if yes, then pls also suggest a cheap & vfm PSU /SMPS.
