For 5 years I have had a S939 system and have just made the leap to AM3 Phenom 2 x6 1055T. I have ordered most of the parts (Ontario prices and so new tax) I need but could use some help in finding two ATI chipset video cards for crossfire and possibly a heat sink and fan.
The parts i have ordered are:
HDD $60 Free shipping for entire order:
Fans (9) $36:
Ram cooler $10:
I bought the CPU and motherboard as a bundle:
$327 at time. CPU:
Thermal paste 10$ and free shipping:
Please comment on my choices so I can learn for next time.
So now I need help in choosing a video card or two. From what I have seen, crossfire seems to make a lot of sense for newer games from a price to performance perspective. Also, I do not know how well the stock hsf on the 1055T performs. I do intend to overclock later (I have never overclocked before).
Crossfire makes a lot of sense if the individual GPUs are still relevant horsepower wise when in CF (sum price point < current single GPUs offering similiar frames in games) and when your game/s scale well in CF mode If i were you i'd have gone
Ya i do want to crossfire later and so I am glad I went with the 890 instead of 870 [1 x PCI Express x16 slot, running at x16 (PCIEX16)
1 x PCI Express x16 slot, running at x4 (PCIEX4)]
I do like the performance of the 4850 and they seem to xfire well. Then again DX11 seems nice (from the bad company 2 comparison videos I saw).
The one thing that scares me is getting a VC with an obsolete or soon to be obsolete shader model (5 years ago i bought the X800XL which was a great card at the time and still plays TF2 well but it could not player lower quality games that had a higher Shader Model not long after I bought it)
Is there a new change in shader model coming soon that I should worry about?
PS I am still bitter about the S939 thing (the best cpu i could find cheap was a 3800 x2 as i didnt felli like getting a new motherboard so soon)
I am heavily considering two Gigabyte 4850 in crossfire (512mb each) as I found them for $95 (Canadian).
The benchmarks look great for dx10. The 5000 series looks terrible for current price/performance in dx10 games compared to 4850s.
However, I have been reading that dx10 was not such a big deal, and that dx11 is expected to become a lot more popular. So my interest in dx11 was raised. I have about tessellation in dx11 and that it is not found in dx10. Is tessellation an important feature. The benchmarks for AVP dx11 Tessellation seemed to destroy the crossfire 4850 (only slightly ahead of a single 4850). The single 4850 was close to a 5770, but the crossfire 5770 smoked the crossfire 4850 (close to double).
I know the 4850 uses shader model 4 and the 5000 series uses sm 5. Where I am, if I bought two 5770s the cost would be approx. $320-350 while the two 4850 = $190. The difference is $130 -160. If I went with the 4850s is it likely they would last for two years (or 1.5)? The savings could be put into better cards later as the 5770 are underwhelming for their price (I don't need eyefinity)
I could see myself waiting until the 6000 series came (by that time more dx11 games would be here too), but am not sure if the crossfire 4850s would last.
