hello guys. :hello: 
i want to change my XFX HD4850 512MB DDR3 , but im not sure which card i should buy.....between this two card :- " HIS HD5770 1GB DDR5 128-bit " or
" Sapphire HD4870 VaporX 1GB DDR3 256-bit "

actually im not really understand what is the difference between 128-bit card and 256-bit card.....please, anybody can help me to choose :wahoo: 

hey melayugamer
Upgrading from a 4850 to a 4870 or even to a 5770 won’t be much of an improvement, barring getting DX11. A 5770 currently performs just under the 4870 and indeed will improve with later driver updates.
The difference between 128 bit and 256 bit would be like, in a metaphor, one freeway lane compared to two lanes. And the frequency at which cars are moving on the lanes is the clock speed of the memory. Dono if this helps but it’s the best I can come up with.
My advice to you is not to buy/compare cards based on if one has faster memory, # of SPs or clock rate or most of the things listed in the products specifications (except maybe the amount of ram) but to look at reviews and actual FPS carts comparing one to another. Why? These cards where specifically designed to be bottlenecked in games to pump out a predictable (and limited) amount of performance for its specific price range. Thus we (the consumer) can safely assume that the 5750 performs less than the 5770 < 5850 < 5870.

Grab the Hd5770. You won't regret it.


Even better, get another 4850... right now there is not a single DX11 games, and until there is a real one, you 2 4850 in crossfire will be enough.

For your information, 2 4850 in crossfire is 11% slower than 2 4870 in crossfire. It's a lot of power for that kind of cost. I got my 2 OC 4850 for a mere 165$ and I got a stronger system than one who used a GTX285.

crossfire???
hmm....im the not-computer-guy person ;) 
but i know what is crossfire....
dont want take any risk with this crossfire....
juz wanna have a pc that can play game such as MWF2,grid ect

anyway...thanks redgarl for your opinion :D 

hello guys...
i just have my hd5770 yesterday... :bounce: 
overall....this card pretty good but in GTA IV in the default setting it cannot full the bar
( i do think that this damn game is very unoptimised :(  )

in COD modern war fare 2....wow its really *boom* :kaola:

In GTA IV you should probably have a great CPU. That game specifically relies heavily upon the CPU.


yeah shadow187...i think so....my CPU just 2.6GHz (its AMD Phenom x4 BE ).....
dont have budget to get highest CPU......still in study :pt1cable:  hahahaha

Your CPU looks great, unless it's the first-generation of phenoms.

try overclocking a modest 400mhz; this shouldn't require anything other than a multiplier adjustment. See if you get more than a 5-frame increase.

Also for GTA-IV you need more than 1GB of VRAM / video memory to allow maximum view distances.


more than 1GB ????
dude......here in my place 1GB videocard really hell price....
student like me....take 1GB videocard will make my life for this 2 or 3 month s**k !!!
no dating with my girl! no hang up with friend! no this and that :cry:  hmmmmm.....

frankly said.....
i dont know this overclocking stuff :cry: 

but....maybe someday i will learn more about this overclock skill :D  hehehehe
