Oh my, for the last time:
smaller power supply - > NO OC ! (absolutely)
Cheap latest standards card (read DX11, HD 5670) !> good proven albeit old standards card(read DX10, 4850)

@wck123456
GDDR3 + 256bit interface >>> GDDR5 + 128 bit interface.
(GDDR5 is low latency, low voltage but does not have 2x performance gain on GDDR3, but you have a 2x bus width in case of 4850. Simply put, what is the use of fast memory or a lot of memory if the bus is not wide enough to carry it?
Think of very high and large water tank with a 1 inch pipe, now compare with a half height smaller tank of 2 inch pipe. Which one do you think will give more water per sec?)

Re: Is Psu Enough for These Cards?

Nice example but GDDR5 has more memory power...

Now i will give u an example...all 3(4850, 4870 and 4890) have 800 SP BUT, 4870 is faster than 4850 because of GDDR5 and 4890 has higher clocked GDDR5 so that its even more powerful. And all of them are 256-bit. Just having 256-bit is not enough! and i agree that 4850 1GB will help him later with big res but he wont be able to play any future games at max! So why not buy a 4770?

---------- Post added at 09:58 PM ---------- Previous post was at 09:53 PM ----------

@others: U CAN OC ON A 400W. I had an npower 450W before.. i had OC'ed my phenom to 3.2Ghz and overclocked the card to 925/925. No problem whatsoever. I just got a new PSU as i had CF'ed the 4770's for some time

Whats more memory power:S??

4870 is not faster coz of gddr5 alone. major performance is coz of the higher clock speed differene between 4850 and 4870
even there was a flavor of 4850 by palit which used gddr5 memory still lagging behind the 4870. On contrary if you oc the 4850 to 4870 clocks it almost matches up with 4870 benches iirc.

Re: Is Psu Enough for These Cards?

thats what m trying to say... by GDDR5 the whole memory mhz multiplies by 4 whereas in GDDR3 its just x2. So u gain more performance. 4870 is just faster cause of higher clock and GDDR5. End of all discussions.

Yes memory power it is
No offence dude, but you just demonstrated the perfect example. Of wait a sec, half baked knowledge!
You ought to research better my friend. Read the part about RV770 core that you talked about in more detail and then talk.
In fact read some reviews of HD4850 and HD4870 and you'll know.

Re: Is Psu Enough for These Cards?

ok,here are the settings-
resolution:1440X900
settings:very high
aa: no aa
now tell me which card will give more fps and how much more?
+tell me can i OC the 4770 with cx400 psu safely to reach as much as performance of hd 4850;i do not have some special cooling methods....
some say that the hd 4770 oc'ed can outperform hd 4850...

---------- Post added at 01:36 PM ---------- Previous post was at 01:30 PM ----------

yeah,u ppl were 100% righ about PSU,minw is a crappy inall one bheapo.i had brought it for Rs.800.!
becoz of this PSU i could not OC my phenom ii to 3.8 ghz,but in my friend's home i was able to oc his dual core to 3.6 ghz easily with the software.
Hey,i heard that mobo also causes lag and it also bottlenecks some good systems?
will my mobo bottleneck my sys?
i hope no......coz its my fav mobo Biostar TA790GXBE

WRONG
n WRONG .. as wingzero said 4870 n 4890 are faster than 4850 coz of higher clock speed and NOT COZ OF THE GDDR5 .. even if 4850 comes with GDDR5, like the 1 palit released .. it's still slower !!!

And DON'T advise members to OC with lower watt PSU. U can do what U wanna do with Ur H/.W .. but I cannot let U misguide members coming here for advise. No effing way !!!

Again, U R WRONG!. I repeat .. 4870 n 4890 are faster than 4850 coz of higher clock speed and NOT COZ OF THE GDDR5

Totally irrelevant .. that image explains inter-GPU communications between the two 4870 cores of the ATI Radeon HD 4870 X2 with 2 GB GDDR5 .. n has nothing to do with the discussion here.

And, plz note: ALL OFFENSE INTENDED !!!

Again, as a mod, its my duty to not let U misguide our members. I'm gonna ve a hawk's eye on all Ur post now on. If U know whats better for U, U'll limit the nonsense, if U can't stop it. Now, I'm off to reply to Ur other post regarding the VIP PSU .. but 1st!

@ sagnik -> if I were U, I'd save some more money n get the 5770/GTX450 with the CX400 as I hate buying a generation old GPU. Also, 55/5600 series are not at all good for gaming n if there was a choice between 55/5600 n a generation old 47/4800, I'd go for the generation old 47/4800 for gaming !!! If I can't afford a 5770/GTX450 then I would get the 4770, just coz *IMHO* 4850 + CX400 is walking on the edge. Ofz 4850 + VX450 is better than 4770 + CX400

And plz don't try n OC with the CX 400 .. ofc VX450 is cool as its underrated (it can supply well over 500Ws of power)

BTW, unlike the 5000 series, 4800 series are comparatively much more power hungry and HOT (not the cool abbreviation hawt) .. they actually produce much more heat than the 5series as well as the 40nm 4770s. So, stop getting more confused and get something quick
