my current rig is
32GB RAM DDR4 3600
WQHD (and VR Quest 2)
Time for me to upgrade my almost 3 yr old 2070S (still capable of running MSFS fine). Now battling myself - should I go for 4080 as it maxes Quest 2 without problem or is it better to go for 4090? When it comes to $$ I am ready to go for the 4090 price tag (including PSU change) but still hesitating as this GPU will be more expensive than my whole build that I have built before (previously on 3700x and 16GB).
4080 + PSU would cost me about 1600 euro
4090 + PSU would cost me 2100 euro
What would you do? Appreciate feedback.
Do you really need a new PSU? I am also battling with the decision for the two, but I am not going to replace my PSU. When I go for a 4090, I will simply reduce power target down to 70-80%. Enough reports that this results in a performance loss of max. 5%, fine for me, if power draw is down 25-30% on the other hand and enabling my Straight Power 11 Gold 750W to cope even with a 4090 easily.
Currently I have 650W PSU which is meh… for 4090 for sure (I know it is possible but well… ), guess 4080 would be able to work so new PSU would not be required. It makes 4080 a bit cheaper but… I feel 4080 is so overpriced for performance that it gives comparing to 4090 which is still high-priced
I’ve read a number of posts that say that radically upgrading either a CPU or a GPU results in stuttering, especially in a VR headset. I’s like a game of teeter-totter…upgrade one and you have to upgrade the other. It doesn’t really make sense to me, but the technical ‘jargon’ is that a more powerful GPU makes the CPU work harder, and vice versa. Maybe it’s a question of code optimization needing to improve. I don’t know.
As to your original question, Until I could afford to build a new system around the 7800X, I would save money and get the 4080. But that’s just me.
EDIT: Actually, I might go for the AMD RX 7900 XTX for about the same price as the 4080. 24GB VRAM vs. 16GB, and it’s getting good reviews. I believe AMD solved its driver problems a while ago.
for the quest, you dont need a 4090.
all from 3080/ti to 4070/4080 should be good enought
If money is not the Problem, i would go to 4080, more futuresafe.
